Stainless steel flat bar is a solid rectangular profile manufactured by hot rolling, cold drawing, slitting stainless steel coil or shearing stainless steel plate.
Its flat surfaces and straight edges make it convenient for welding, bolting, drilling and connecting with stainless steel plates, pipes, channels, angles and other structural components.
Stainless flat bar is commonly selected when a project requires a combination of corrosion resistance, structural strength, simple fabrication and an exposed metallic appearance.
Hot rolled stainless flat bar is commonly supplied in medium and heavy dimensions. It normally has a No.1 or pickled surface and is suitable for structural supports, machinery frames and industrial fabrication.
Cold drawn flat bar provides tighter dimensional tolerances, straighter edges and a smoother surface. It is suitable for precision machinery, equipment components and visible fabricated products.
Slit flat bar is produced by cutting stainless steel coil into narrow widths. It is commonly used for light supports, brackets, decorative trim and continuous production requirements.
Sheared flat bar is cut from stainless steel plate. It provides flexibility for customized widths, thicknesses and short production quantities.
Polished flat bar has a processed surface designed for architectural, decorative, food-processing and visible equipment applications.
Grade 304 provides a practical combination of corrosion resistance, weldability, formability and mechanical strength. It is widely used for machinery, architecture, food equipment and general fabrication.
Grade 304L contains less carbon than standard 304 and is frequently selected for welded structures where improved resistance to sensitization is required.
Grade 316 contains molybdenum and generally provides improved resistance to chloride-containing and more corrosive environments compared with grade 304.
Grade 316L combines improved corrosion resistance with a lower carbon content. It is commonly used for chemical facilities, coastal structures, marine equipment and welded process systems.
Grade 201 can provide an economical solution for indoor structures, furniture, decoration and applications with lower corrosion exposure.
Grade 310S is commonly considered for heat-resistant equipment and elevated-temperature structural components. Final suitability depends on temperature, load and operating atmosphere.
Duplex 2205 provides higher strength and improved resistance to chloride stress corrosion cracking compared with many standard austenitic grades. It is used in chemical, marine and demanding industrial environments.
Stainless steel flat bars are used for machine bases, frames, equipment supports, brackets, mounting plates, reinforcement members and general fabricated components.
Food and beverage equipment manufacturers use stainless flat bars for conveyor supports, processing tables, equipment frames, guard structures and hygienic production systems.
Chemical and process industries use suitable stainless grades for pipe supports, tank accessories, platforms, equipment frames and corrosion-resistant structural components.
Architectural applications include façade supports, decorative trim, door frames, handrail components, partitions, shop fittings and visible structural details.
Marine and coastal projects may use 316L or duplex grades for boat fittings, dock equipment, support structures and components exposed to humid or chloride-containing environments.
Suitable stainless steel grades provide resistance to moisture, atmospheric corrosion and many industrial environments without requiring galvanized or painted surface protection.
The solid rectangular cross section provides reliable strength and rigidity for supports, brackets, frames and reinforcement components.
Flat surfaces make the material suitable for welding, bolting, drilling, punching, machining and connection to other components.
Industrial, brushed and polished finishes can be supplied for structural, hygienic, architectural and decorative requirements.
Width, thickness, length, edge condition and tolerances can be selected according to production drawings and equipment requirements.
Stainless steel can reduce repainting and surface maintenance requirements when the correct grade is selected for the service environment.
Hot rolled stainless flat bar is suitable for structural and industrial applications where heavier dimensions and standard commercial tolerances are acceptable.
Cold drawn flat bar provides tighter tolerances, improved straightness, cleaner edges and a smoother surface for precision or visible components.
Selection should be based on required dimensions, tolerance, surface appearance, machining requirements, order quantity and project budget.
Slit flat bar is produced from stainless steel coil and is generally suitable for thinner dimensions, continuous production and longer quantities.
Sheared flat bar is cut from plate and provides flexibility for thicker products, wider bars and customized short-run dimensions.
Slit edges may show slight edge rounding or burrs depending on the process. Sheared edges may require deburring, grinding or machining when cleaner edges are required.
Grade 304 is widely used for general industrial, architectural, food-processing and equipment fabrication under normal atmospheric and mildly corrosive conditions.
Grade 316L contains molybdenum and generally provides improved performance in coastal, marine, chemical and chloride-containing environments.
Grade 304 is usually the more economical choice for general applications, while 316L is selected when the service environment requires increased corrosion resistance.
Carbon steel flat bar provides economical structural strength but normally requires painting, galvanizing or another protective coating in corrosive environments.
Stainless steel flat bar provides integral corrosion resistance and a clean metallic surface. It is suitable for food equipment, chemical processing, coastal projects and exposed architectural components.
Material selection should consider initial cost, corrosion exposure, hygiene requirements, maintenance frequency, appearance and expected service life.
No.1 and pickled surfaces are commonly used for hot rolled industrial flat bars where appearance is not the primary requirement.
2B and BA surfaces may be available for slit flat bars manufactured from cold rolled stainless steel coil.
Brushed, ground and polished surfaces can be supplied for architectural, decorative, food-processing and visible equipment applications.
Customers should specify the required finish, polishing grit, polishing direction, acceptable scratches and whether protective film is required.
Henan GDD can arrange stainless steel flat bar cutting according to customer-required installation or production lengths.
Drilling, punching, bending, welding, grinding, polishing and drawing-based fabrication can also be discussed for machinery parts, brackets, supports and finished assemblies.
Customers should provide drawings showing the material grade, width, thickness, length, hole diameter, hole position, tolerances, surface finish and required quantity.
Stainless steel flat bar can be welded using a qualified procedure suitable for the selected grade, material thickness and final service environment.
Welding consumables should be compatible with the base material. Heat input, distortion control, joint preparation and surface cleanliness should be controlled during fabrication.
Welding discoloration, scale and contamination can reduce local corrosion resistance. Grinding, pickling, passivation or another suitable post-weld treatment may be required.
Selection should consider stainless steel grade, production method, width, thickness, length, edge condition, tolerance, surface finish and final operating environment.
Grade 304 is suitable for many general applications, while 316L is considered for coastal, marine and chemical conditions. Heat-resistant or duplex grades may be required for specialized environments.
