Steel in Sheet Metals
Longwang provides steel sheet metal fabrication services, including laser cutting, bending, stamping, welding, powder coating, and assembly, with strict quality control to ensure durability.
Steel is one of the most widely used materials in sheet metal fabrication because it offers high strength, good formability, reliable weldability, and excellent cost efficiency. It can be laser cut, punched, bent, stamped, welded, riveted, finished, and assembled into durable custom components for industrial and commercial applications.
Different steel options, including mild steel, carbon steel, galvanized steel, stainless steel, alloy steel, spring steel, and tool steel, can be selected based on strength, corrosion resistance, surface finish, and cost requirements.
At Longwang, we provide custom steel sheet metal fabrication for enclosures, brackets, panels, frames, cabinets, guards, chassis, equipment covers, automotive parts, smart home components, and non-standard industrial parts. With laser cutting, CNC punching, bending, stamping, welding, powder coating, automated spraying, assembly support, and strict quality inspection, we help customers produce reliable steel sheet metal parts from prototype to batch production.
Mild Steel Sheet Metal is a cost-effective low-carbon steel with good formability, weldability, and reliable strength. It is widely used for brackets, panels, frames, cabinets, covers, chassis, and general industrial sheet metal parts. Longwang fabricates mild steel parts through laser cutting, punching, bending, stamping, welding, powder coating, assembly, and strict quality inspection.
Galvanized Steel Sheet Metal is coated with a protective zinc layer to improve corrosion resistance and surface durability. It is suitable for outdoor enclosures, HVAC parts, ventilation panels, electrical cabinets, brackets, covers, and industrial components. Longwang provides cutting, bending, stamping, welding, coating, and assembly support for custom galvanized steel parts.
Stainless Steel Sheet Metal offers excellent corrosion resistance, clean appearance, and long-term durability. It is ideal for enclosures, panels, brackets, cabinets, medical equipment parts, food equipment components, smart home hardware, and industrial assemblies. Longwang fabricates stainless steel sheet metal parts with cutting, bending, welding, finishing, assembly, and strict inspection.
Spring Steel Sheet Metal is a high-carbon steel designed for elasticity, high yield strength, fatigue resistance, and wear performance after heat treatment. It is commonly used for springs, clips, washers, elastic brackets, blades, retaining parts, and high-resilience industrial components. Longwang supports custom spring steel sheet metal fabrication for demanding functional applications.
Steel sheet metal parts often require surface finishing to improve corrosion resistance, appearance, durability, and product performance. At Longwang, we provide multiple finishing options for steel parts after laser cutting, CNC punching, bending, stamping, welding, and assembly.
As Machined
Standard finish, surface roughness of 3.2 μm (126 μin), removes sharp edges and deburs parts cleanly.
Tumbling
Utilizes barrel or vibratory processes with abrasives to smooth and polish the surface of parts.
Heat Treatment
Alters the physical (and sometimes chemical) properties of a material to achieve desired mechanical properties.
Anodizing
Electrochemical process that forms a durable, corrosion-resistant oxide layer on the surface of metals.
Teflon Coating
Applies a protective layer of PTFE to reduce friction and enhance corrosion resistance.
Electroplating
Electroplating is an electrochemical process that deposits a protective metal layer onto a conductive surface.
Polishing
Polishing smooths a surface to improve shine, reduce roughness, and enhance appearance.
Powder Coating
Powder coating provides a durable, scratch-resistant finish with excellent corrosion protection and a clean, attractive appearance.
Brushed
Brushed finish creates a refined linear texture with a modern, metallic look.
Steel is one of the most practical materials for sheet metal fabrication because it combines strength, availability, formability, weldability, and cost efficiency. It is suitable for both prototypes and batch production, but different steel grades require different surface protection and process control.
