Stainless Steel Angle Bar: Sizes, Grades & Where to Buy

Stainless steel angle bar: A Practical Buying Guide

Looking for a reliable stainless steel angle bar supplier? Huaxiao Stainless keeps 100,000 tons of inventory, ships in 15 days, and is certified to ISO/TS16949. Before you request a quote, here is what actually matters when specifying and sourcing stainless steel angle bar.

Why Choose Stainless Steel Angle Bar

A stainless steel angle bar (L-profile) turns flat stock into a structural member. The 90-degree bend gives two bearing surfaces, so a single piece handles both load transfer and corner protection – frames, supports, brackets, guards and trim all start as angle. In 304 it resists indoor and mild-outdoor corrosion for decades; in 316 it shrugs off salt spray in coastal and marine service.

Angle is supplied as equal-leg (both sides the same) or unequal-leg (one side wider) for applications where load is asymmetric. Because it is rolled or drawn to tight tolerances, it welds and bolts cleanly into frames without shimming.

Specifications, Sizes & Surface Condition

We supply angle bar to ASTM A276 / A484 and EN 10056. Equal-leg sizes run from 20×20 mm up to 200×200 mm, unequal-leg from 30×20 mm to 200×150 mm, leg thickness 3-20 mm, in 6 m lengths or cut to your drawing.

• Form: equal leg or unequal leg
• Condition: hot rolled, laser-fused (for clean corners), or cold drawn for tight tolerance
• Surface: pickled, brushed (No.4), or polished to Ra 0.4
• Also available: stainless channels, flat bar and T-sections from the same line

304 typical: Cr 18.0-20.0%, Ni 8.0-10.5%, tensile 515 MPa min. 316 adds 2-3% molybdenum for chloride resistance (PREn ~24-25).

Stainless Steel Angle Bar Price Factors

The stainless steel angle bar price per kg is set mainly by grade, leg size and thickness. 316 costs 25-40% more than 304 because of molybdenum; thicker legs and wider unequal profiles carry a rolling premium; laser-fused (weld-seam) angle is priced above hot-rolled for its clean corner and lower distortion.

• Grade: 304 baseline, 316 marine premium, 430 cheaper for indoor only
• Size: very small (under 25 mm) and heavy (over 150 mm) legs both add cost
• Tolerance: cold-drawn / laser-fused cost more than hot-rolled
• Quantity: full-bundle pricing beats piece-cut pricing

Send us the leg dimensions and grade and we will advise the most economical stock size to minimise offcut scrap.

Common Applications

Angle bar frames machine guards and equipment racks, reinforces handrails and balustrades, braces structural steel in buildings and façades, forms shelving and racking, supports solar and signage structures, and is specified for marine platforms, food-line frames and architectural trims where both strength and corrosion resistance are required.

How to Choose a Reliable Supplier

Two checks matter for angle. First, verify the grade on delivery with PMI (positive material identification) – cheap 304 is sometimes substituted into a 316 order, and only an analyser catches it. Second, check the leg-angle tolerance on the certificate, because a few degrees off makes frames rack. For marine use, insist on 316 with the molybdenum confirmed.

A reliable stainless steel angle bar supplier welcomes both checks. Huaxiao Stainless keeps 100,000 tons in stock, ships in 15 days, and holds ISO/TS16949 certification with full heat traceability from mill to your dock.
