Stainless steel profile is a long strip of material with a specific shape made of stainless steel material, which is widely used in many industries such as construction, machinery, automobiles, ships, etc. It is usually made into different cross-sectional shapes through processes such as extrusion, rolling or stretching, including angle steel, square tube, rectangular tube, U-shaped steel, C-shaped steel, etc.
Common types
Depending on the cross-sectional shape and purpose, the common types of stainless steel profiles include:
Stainless steel angle steel: usually L-shaped cross-section, widely used in building support structures.
Stainless steel square tube and rectangular tube: commonly used in construction, home appliances, furniture, mechanical structures, etc.
Stainless steel H-shaped steel and I-shaped steel: suitable for load-bearing structures.
Stainless steel channel steel: used for structural frames and supports.
Stainless steel round tubes and round bars: widely used in machinery, chemical industry, decoration and other fields.
Material characteristics
The main material of stainless steel profiles is stainless steel, which is widely used due to its excellent corrosion resistance, oxidation resistance and high strength. Common types of stainless steel include:
304 stainless steel: strong corrosion resistance, widely used in food, medicine, chemical industry and other industries.
316 stainless steel: has stronger corrosion resistance, especially suitable for marine environment.
201 stainless steel: economical material, slightly less corrosion resistant than 304 stainless steel, but still suitable for general construction and industrial use.
Advantages
Strong corrosion resistance: stainless steel profiles are resistant to oxidation and corrosion, suitable for use in harsh environments.
High strength and good wear resistance: suitable for structural parts that bear large loads.
Beautiful: high surface finish, suitable for decorative structures.
Environmental protection: stainless steel can be recycled and meets environmental protection requirements.
Application areas
Stainless steel profiles are widely used, mainly including:
Construction industry: used for steel structure buildings, curtain walls, stair handrails, railings, etc.
Machinery manufacturing: used for frames, support structures, mechanical parts, etc.
Automobile industry: used in automobile exhaust pipes, body frames and other parts.
Food and pharmaceutical industries: due to its corrosion resistance and hygiene, it is often used in equipment manufacturing and surface decoration.
Processing and Surface Treatment
During the processing of stainless steel profiles, different surface treatments may be performed, such as:
Polishing: to make the surface smooth, increase aesthetics and stain resistance.
Wire drawing: to produce fine line textures, which are decorative.
Sandblasting: used to prevent surface scratches and provide higher surface hardness.
Coating treatment: such as PVD coating, provides additional anti-corrosion protection.
