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.
About 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 urable 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.

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.
HOW DOES STRATUSTEEL BENEFIT YOU?
ENGINEERS: Explore new design options with lighter, more streamlined products. Switching to Stratusteel
from ASTM A500 Grade B can enable a wall thickness reduction of 35%. It may even enable you to reduce the number of steel components in your assembled product.
PURCHASING AGENTS: Every pound of steel you don’t have to buy is a direct savings for your bottom line.
SHIPPERS: Smaller, lighter products mean fuller shipments and lower shipping costs. This enables you to
get the most out of every freight mile—ultimately reduces demands on drivers’ time, and fuel consumption.
MARKETERS: With Stratusteel, your product may potentially be positioned as the lightest, strongest of its kind on the market.
Finishes available:
- Post-pickled in oil
- EPS (Eco-Pickled Surface)
