316L Marine Grade Stainless Steel Channel Anti Seawater Corrosion

Product Description

Product Description

    Introducing our stainless steel channel, available in various grades to suit different applications. The 304/304L option is ideal for general engineering projects, offering excellent corrosion resistance. For coastal or chemical environments, the 316/316L variant is the top choice. Economical indoor light structures can benefit from the 201 grade, while high-temperature furnace linings require the durability of 321/310s steel.

    Choose the black finish for hot-rolled surfaces in construction, pickled for a white surface perfect for industrial equipment frames, or bright for food and pharmaceutical equipment. Versatile and durable, our stainless steel channels are designed to meet your specific needs with quality and precision.

Excellent corrosion resistance
    Stainless steel channel contains chromium element, forming a dense passive oxide film on the surface. It resists rust, acid, alkali, salt water and atmospheric corrosion, no surface rust even used in humid, coastal and chemical environments.
    High mechanical performance
    Good tensile strength, yield strength and impact toughness. It maintains stable mechanical properties under low and high temperature conditions, not easy to deform or break under load.
    Long service life & low maintenance
    No anti-rust paint or anti-corrosion coating needed. Only simple cleaning is required in daily use, greatly reducing later maintenance cost and labor.
    High temperature & low temperature adaptability
    Does not soften at high temperature, will not become brittle at subzero temperature, suitable for extreme temperature working conditions.
    Hygienic & pollution-free
    Smooth non-porous surface, hard to breed bacteria, non-toxic and non-polluting, compliant with food, medical and drinking water industry standards.
    Beautiful metallic luster
    Natural silver metal finish, can be directly used as decorative structural parts without extra painting, improving overall appearance of projects.
    Good machinability & weldability
    Easy to cut, bend, punch and weld; stable welding performance without cracking after forming.
    Light weight with high bearing capacity
    Special C/U channel cross-section provides strong structural rigidity, lighter than solid steel bar while supporting heavy loads.

Features

    Standard U/C shaped cross-section, uniform wall thickness, straight flat flange and smooth surface.
    Stable chemical composition (304, 316L, 201, 310S common grades), consistent material performance per international standards ASTM, EN, GB.
    Two production types: hot rolled stainless channel and cold formed stainless channel. Hot rolled for heavy load industrial use; cold formed for thin-wall light structural & decorative use.
    Precise dimensional tolerance, flatness and straightness, convenient for assembly, connection and bolt fixing.
    Anti-oxidation, anti-scaling, no rust spots under long-term outdoor exposure.
    Recyclable 100% green metal material, no environmental pollution after scrapping.
    Different surface finishes available: No.1 hot rolled black surface, 2B bright cold rolled, BA mirror finish, brushed finish.

Manufacturing Process of Stainless Steel Channel

    Raw Material Inspection 
    Test stainless steel ingot or stainless steel slab, check chemical composition, hardness and surface defects to confirm compliance with material standards.
    Heating Furnace Heating 
    Put qualified steel slabs into heating furnace, heat to 1100–1250℃ evenly to soften steel for rolling forming.
    Rough Rolling 
    Send hot slab into rough rolling mill, repeatedly press to reduce thickness and preliminarily form U-shaped channel outline.
    Finish Rolling 
    Multiple passes of precision finish rolling, shape standard channel cross-section, control wall thickness, flange width and height to meet size tolerance.
    Cooling 
    Transfer hot rolled channel to cooling bed for air cooling to room temperature to stabilize internal metal structure.
    Straightening 
    Use straightening machine to correct bending, twisting and uneven flatness after cooling.
    Cutting to Fixed Length 
    Cut channels into customer required lengths by flying saw or cold cutting saw.
    Surface Polishing / Descaling 
    Remove high-temperature oxide scale by pickling, sand blasting or grinding; provide customized surface finish as order demand.
    Inspection & Marking 
    Full inspection of dimension, mechanical property, corrosion resistance and surface quality; stamp grade, specification, heat number on product surface.
    Packaging & Storage 
    Bundle finished channels with steel strips, label specifications, store in dry warehouse for delivery.
