  • Wide ranges of yield strengths; 46 KSI to 110 KSI.
  • Tighter tolerances, sharper corners and straighter tubes.
  • Less residual stress on the steel
  • Widest variety of custom sizes and lengths, including metric sizes and cut-to-length options
  • Special packaging

STRATUSTEEL

We’re Taking High-Strength, Lightweight Steel to New Heights

Stratusteel® from Bull Moose® is revolutionary hollow structural steel tubing that’s three times harder than conventional steel, and achieves strength ratings in excess of 100 and 110 KSI…at a weight that’s as much as 35% below other steel.

This robust technology enables cranes to reach higher, trailers to carry more weight, rescue ladders to extend farther — all without compromises in strength.

Bull Moose Tube HSS ProductionAbout The Product

STRONGER: Stratusteel® achieves strength ratings from 100 to 110 KSI, compared the 50 to 80 KSI ratings of conventional steel. Produced in accordance with ASTM A1112, our product is stronger — which means you can load more or extend further.

LIGHTER: Living up to its stratus-cloud namesake, Stratusteel® is as much as 35% lighter than standard steel products.

TOUGHER: Stratusteel® is 3x harder than standard steel as measured by the Rockwell hardness scale. As a result, products made of Stratusteel® have an impact-resistant toughness that enables them to take a beating and look newer, longer. This hardness also enables extendable products (such as booms and fire truck ladders) to extend farther without sway or bounce.

CREATES VALUE FOR YOU IN SIGNIFICANT WAYS: For truckers, less weight = more freight. For booms, cranes, and ladders, it’s stronger so you can extend longer. For every application, it performs as some of the toughest, most durable steel ever, prolonging the life and value of heavy-duty equipment.

CURRENT APPLICATIONS: Military vehicles, launch pad scaffolding, ladders, booms, agricultural equipment, heavy haul trailers.

About The Name

We presented several possible product names to hundreds of opinion-leaders in the transportation industry, and let them vote for their favorite. The final selection: Stratusteel®. Named after the steel-gray stratus clouds that can span the horizon, Stratusteel® is just as far-reaching and nearly as light.

WEATHERING GRADE STEEL TUBE

The Low-Cost, No Maintenance Alternative to Outdoor Applications

With the rising cost of galvanized steel, it’s good to know there’s a solid substitute: Weathering Grade steel tube from Bull Moose®.

Compare this stock to COR-TEN® and other ASTM A847 options, and you’ll find that our Weathering Grade steel delivers equivalent performance for heavy weather environments…cost-effectively.

Over time, the surface of this alloy steel develops a stable, light-brown patina that protects it from corrosion—and eliminates the need for painting and re-painting.

Its durability and 50 KSI strength make it ideal for applications such as walkways, bridges, railings, and other structures that are directly exposed to the elements.

Bull Moose Weathering Grade stock is readily available in multiple lengths, shapes, and wall thicknesses to fit an extensive range of projects.

Product Details

  • Produced per ASTM A847, which mirrors ASTM A500 (plus atmospheric-corrosion-resistant steel)
  • 50ksi min. yield, 70ksi min. tensile, 19% min. elongation.
  • General applications: bridges, utility/light poles.
  • Normally in stock:
    • 3/16”
    • 1/4”
    • 3/8″
    • (Custom sizes: inquire on lead time)
  • Uncoated weathering steel typically provides initial cost savings of 10-15% by avoiding the expense of painting, and savings of at least 30% over the life of the structure.
  • The steel’s weathered finish provides a natural look for outdoor environments, and because it is permanent, it does not require either VOC paint or blasting—both of which can be harmful to the environment.

  1. Fabrication Considerations 8
  2. Final Considerations 8

Stratusteel™ hollow steel tubing from Bull Moose is stronger than steel, and lighter than aluminum configured to bear the same load. As a result, you can reduce the weight of your design by as much as 35% while getting the strength and other benefits  of steel. With Stratusteel, your designs will be dramatically lighter, stronger, and more efficient!

Introduction 

Welding  of Stratusteel will be different than typical A500 50MY – 80MY tubing. Stratusteel is greater  than or equal to 100MY, and as a result, welding requirements are slightly different. When  welded  properly, Stratusteel will ensure long-lasting performance  while making your designs lighter, stronger  and more efficient to manufacture.

1. Preparation 

All well-established methods or processes of preparation can be used with Stratusteel.   However, attention should be paid to any potential buildup of materials on the surface of weld joint, such as thin oxides films from thermal cutting. Make sure all joints are well cleaned prior to welding.  If using a plasma cutting for joint preparation, oxygen should be used to minimize risk of porosity in the weld material during welding. It is also possible to use a grinding method, which would remove the risk of porosity in the weld material. It’s recommended to grind down by at least 0.2mm if using this method post plasma cutting. 

2. Welding  

All common fusion welding methods can be used for welding Stratusteel, such as: 

  • MAG/MIG – Welding 
  • MMA-Welding 
  • TIG-Welding 
  • Plasma Welding 
  • Submerged Arc Welding 
  • Laser Welding 

While other methods can be used, these are the most common for Stratusteel. Of these, MAG/MIG welding is the most commonly used welding technique known today. When T-joint welds are close to the edge with a thickness ≥ 8 mm, there should be no sharp defects at the edge. Such defects can lead to stresses in the thickness direction, which can lead to cracking during welding. These welds should be avoided. Shearing is not expected in the use of Stratusteel due to its shape and size. However, if shearing is used, welding should not occur near the sheared area, as it gives increases in stress at the shear location (which can lead to cracking at the weld location in contact with the shear location). It’s recommended that if the location must be used, that it’s  thermally cut instead of sheared. 

3. Recommended Welding Materials for Stratusteel

EN 16834(-A) 69X

Table #1: Recommended weld wire for Stratusteel

4. Preheat and Inter-pass Temperature Considerations 

Multi-pass welding may cause the temperature in the welded joint to rise to a level that causes the strength to drop. This is most critical for welds below 500mm, because the temperature will drop between weld bead formations.  The maximum inter-pass temperature for Stratusteel is  100 degrees C.  For short welds, it is recommended to allow the temperature to cool to 150  degrees C prior to starting the next weld bead. For best results, it is recommended for Stratusteel to be at standard room temperature (temp ≥  23 degrees C ≤100 degrees C) prior to welding. 

5. Hydrogen Cracking Risks 

This risk of hydrogen cracking is very low; however, it can occur under very specific conditions. Hydrogen cracking will occur if European Standard 1011-2 is met, whereby a very high hydrogen content > 15 ml/100g of weld metal material and an extremely low heat input of < 0.5Kj/mm are applied, with a combined thickness of 30mm of Stratusteel.  These conditions are very rare— however, it is critical to monitor and prevent these conditions in order avoid risk of hydrogen cracking during welding.  To avoid this risk, it’s recommend that you use weld materials with low hydrogen content ≤ 10 ml/100g weld metal. When welding Stratusteel it’s important to also follow good general welding practice to avoid increased risk of hydrogen cracking. Rules of thumb to follow to minimize hydrogen cracking are:

Minimize the hydrogen content in and
around the prepared joint.
Minimize the stresses in the weld join.
Use the correct pre-heat and inter pass
temperatures.
Do not use welding consumables of a
higher strength than is necessary.
Use welding consumables with low
hydrogen content.
Arrange the weld sequence so that the
residual stresses are reduced during the
welding process along the weld seem nor
in the welded joints.
Keep impurities out of the weld area. Set the gap in the joint to a maximum of
3mm.

Table #2: Rules of thumb for handling prior to welding

 

6. Heat Affected Zone (HAZ) or Soft Zones When using Stratusteel, soft zones can form in the HAZ.  This can happen as a result of changes in the microstructure during welding.  However, if normal heat inputs are used, then these soft zones typically do not influence the strength of the weld.  For example, if an inter-pass temperature of 150 degrees C is maintained using a single pass, then the heat input which would affect Stratusteel could be increased by 10 – 15% for a butt weld, and approximately 40 – 50% for a filet weld. Following the inter-pass temperature limits will reduce if not eliminate any impact in HAZ leading to soft zones.

7. Direction and Passes for Welding When using Stratusteel we recommend that you start your weld bead in the larger section of the parent material and then work towards the joint. For two pass welds we recommend that once at the joint, the welder restart from the larger section going into the joint (as opposed to returning from the joint to larger section).  Please see figure #1 as a representation of starting welds at joint locations.

Restarting second pass welds in the larger parent material allows for inter pass cooling and reduction of stresses at the joint.  If welding a plate, it is recommended that the plate use a  notch of at least 1” in radius at the joint to prevent concentration of stresses at the joint an follow the inter pass recommendations above.

7.1. Welding Parameters Analyzed As part of this guide, extensive thermal analysis was performed in order to generate stress analysis curves and impact of welding conditions.  Below is the table of welding parameters used  for this section:

(i.e., welder speed should still be as above)
Weld Wire Size: .035 weld wire

Table #4: Weld Parameters used during real-world construction of 8-gauge 3”x5” Stratusteel

8.    Fabrication Considerations When fabricating (welding) Stratusteel HSS, consideration should be taken to reduce the residual stresses imparted into the HSS from the shop/field welding process. The weld seam on the HSS should be oriented, if possible, where thermal stresses will not affect the weld seam. For example, orienting the HSS weld seam in a restrained position under a reinforcement plate, bracket, etc., to minimize buildup of residual stresses. Cutouts and holes, where possible,  should be placed away from or opposite the weld seam face.

9.    Final Considerations All steps mentioned above should be taken when welding Stratusteel.  In addition, you should make every effort to have a clean, moisture-free weld area for best results.  Condensation, dirt,  and any other foreign material should be removed prior to welding.  Always monitor and prevent conditions that could cause hydrogen cracking.

The Strongest, Lightest Steel Tubes on the Planet

LIGHTWEIGHT STEEL WITH HEAVYWEIGHT PERFORMANCE

Stratusteel®  is a revolutionary hollow structural steel tubing that delivers an extraordinary set of characteristics:

High Strength = Yield strengths as high as 110KSI, enabling your products to support greater loads and span greater distances.

Light Weight = 35% lighter than an equivalent A500 50KSI product!

2x Harder than Steel = Your products become more durable and sustainable; remain better-looking, longer.

CUSTOM SIZES AND PROFILES

Stratusteel is available in a broad range of standard and metric sizes. But our variable tooling mills also allow for custom tube profiles. We can optimize wall thickness and outer dimensions/contours for your specific needs.

Customizing for your exact application saves you from buying bulkier stock than you really need…making Stratusteel a high value custom product for a standard steel price!

Here’s an example:

Your design shows that a 3.83” x 5.75” x 0.197” HSS will work on your product (weighing 11.98 lbs/ft.).

If the nearest size in conventional HSS is 4” x 6” x .025” (weighing 15.62 lbs/ft.), you’ll experience an unnecessary 23% increase in weight and thus a 23% increase in cost!

Stratusteel would enable you to avoid those increases with efficient, optimal dimensions and weight.

Document Text:

This publication presents tables of dimensions and section properties for rectangular Hollow Structural Sections (HSS) produced by Bull Moose Tube Company.

The dimensions, including nominal width, nominal depth, nominal diameter and nominal wall thickness are subject to the permissible variations stipulated in ASTM A500 “Standard Specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes.”

With today’s manufacturing methods, HSS are produced to more precision than in the past. The strip used to produce HSS is now ordered to thicknesses with tighter tolerances. As a result, ERW HSS manufactured to ASTM A500 will often have a wall thickness close to the Specification allowable value.

In a change from past practice, section property data is now based upon the design wall thickness. The design wall thickness, t, for ERW HSS is less than the specified nominal wall thickness. The design wall

thickness for each HSS size is included in the tabulated data.

The section property data based upon the design wall thickness, t, results in variations in the published area data that do not exceed 3.50% of the data based upon the minimum permissible wall thickness stipulated in ASTM A500. This is consistent with the similar section property data published for hot rolled structural shapes and the manufacturing tolerances associated with those products. The section property data for rectangular ERW HSS are based upon outside corner radii equal to 2.0 times the design wall thickness.

These tables contain all HSS sizes produced by Bull Moose Tube Company as well as current capability to produce sizes. Check with our sales department for current availability.

The more universal terms “Hollow Structural Section” and “HSS” are used in this publication to designate rectangular structural steel tubing. These terms replace “structural tubing” and “pipe,” which had

been used previously.

Document Text:

This publication presents tables of dimensions and section properties for square Hollow Structural Sections (HSS) produced by Bull Moose Tube Company.

The dimensions, including nominal width, nominal depth, nominal diameter and nominal wall thickness are subject to the permissible variations stipulated in ASTM A500 “Standard Specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes.”

With today’s manufacturing methods, HSS are produced to more precision than in the past. The strip used to produce HSS is now ordered to thicknesses with tighter tolerances. As a result, ERW HSS manufactured to ASTM A500 will often have a wall thickness close to the Specification allowable value.

In a change from past practice, section property data is now based upon the design wall thickness. The design wall thickness, t, for ERW HSS is less than the specified nominal wall thickness. The design wall

thickness for each HSS size is included in the tabulated data.

The section property data based upon the design wall thickness, t, results in variations in the published area data that do not exceed 3.50% of the data based upon the minimum permissible wall thickness stipulated in ASTM A500. This is consistent with the similar section property data published for hot rolled structural shapes and the manufacturing tolerances associated with those products. The section property data for square ERW HSS are based upon outside corner radii equal to 2.0 times the design wall thickness.

These tables contain all HSS sizes produced by Bull Moose Tube Company as well as current capability to produce sizes. Check with our sales department for current availability. The more universal terms “Hollow Structural Section” and “HSS” are used in this publication to designate square structural steel tubing.

These terms replace “structural tubing” and “pipe,” which had been used previously.
