Stainless Steel Channel

Stainless steel channels, available in standard and lightweight profiles, provide exceptional load-bearing capacity and corrosion resistance for demanding structural applications. Compliant with ASTM, EN, JIS, and GB standards, these hot-rolled or welded channels are engineered for durability in construction, shipbuilding, and machinery. With flange widths ranging from 50mm to 400mm and thicknesses up to 14.5mm, they outperform traditional I-beams in cost-efficiency by 12–18% due to optimized material distribution.

‌Key Technical Specifications & Compliance‌

‌Material Properties‌:

‌Grade‌	‌Yield Strength (MPa)‌	‌Tensile Strength (MPa)‌	‌Elongation (%)‌	‌Tolerances‌
ASTM A36	≥250	400–550	20–23	±2% height, ±1.5% flange width

Q345B	≥345	470–630	19–21	±2mm thickness, ±3mm length

‌Dimensional Range‌:

‌Size (mm)‌	‌Thickness (mm)‌	‌Weight (kg/m)‌	‌Section Modulus (cm³)‌
50×37×4.5	4.5–14.5	5.8–24.6	12.5–48.3

‌Certifications‌: ISO 9001:2015, SGS, BV, and AWS D1.6 for stainless steel welding.

‌Engineering Advantages Over Competing Profiles‌

‌Corrosion Resistance‌: 316/304 stainless options achieve Class 4 finish (Ra ≤0.4μm) for marine environments.
‌Design Flexibility‌: Lightweight channels reduce dead loads by 15–30% versus standard profiles.
‌Cost Efficiency‌: Hot-rolled production cuts machining time by 25% vs. cold-formed alternatives.
‌Weldability‌: Low carbon grades (C ≤0.23%) prevent carbide precipitation in HAZ zones.

‌Critical Applications & Project Case Studies‌

Stainless steel channels are ideal for:

‌Construction‌: Roof trusses (S355JR, 200×75×11.5mm).
‌Shipbuilding‌: Hull reinforcement frames (ASTM A572, 400×104×14.5mm).
‌Industrial‌: Conveyor system supports (Q345B, galvanized).
‌Infrastructure‌: Bridge guardrails (SS440, 150×75×9mm).

‌Project Highlight‌: In Singapore’s Coastal Terminal, 8,000 meters of 316L channels (16mm thickness) achieved 50-year corrosion resistance in salt-spray zones, reducing maintenance costs by 40%.

‌Customization & Quality Assurance‌

‌Processing Options‌:

‌Cutting‌: Plasma, laser, or saw-cut (±1mm length tolerance).
‌Surface Treatments‌: Electro-polishing (EP) or PVDF coating (35μm DFT).
‌Packaging‌: Waterproof wrapping + steel strapping.

‌Testing Protocols‌:

‌PMI Testing‌: XRF verification of Cr/Ni/Mo content.
‌Hardness Testing‌: 75–85 HRB (Rockwell B scale).
‌Dimensional Checks‌: Laser-guided CMM inspection (±0.3mm accuracy).
