materials
Available materials for sheet metal fabrication
We fabricate sheet metal parts in carbon steel, stainless steel, aluminum, and specialty metals—engineered for strength, precision, and durability. Finishes include powder coating, anodizing, plating, and more.
Carbon Steel
Carbon steel offers high strength, good weldability, and cost efficiency, making it ideal for structural parts, enclosures, and control cabinets. It is often treated with powder coating, electroplating, or electrophoresis to enhance corrosion resistance.
Aluminum
Aluminum alloys are lightweight, corrosion-resistant, and thermally conductive, making them ideal for electronics, communication equipment, and lightweight assemblies. Common treatments include anodizing, sandblasting, and electrophoretic coating.
Stainless Steel
Stainless steel is prized for its corrosion resistance, strength, and sleek appearance. It is widely used in medical devices, food-grade equipment, and high-end enclosures, with finishes like brushing, mirror polishing, and electrolytic polishing.
Other
Specialty metals like copper, titanium, and magnesium are valued for their conductivity, biocompatibility, and strength. They’re used in connectors, precision parts, and aerospace, with treatments like plating and laser marking.
Sheet Metal Fabrication Tolerance Table
Tolerances vary by material and part complexity. Critical features follow customer specs or ISO standards.
| Tolerance Type | Feature | Typical Tolerance Range | Notes | ||||||
| Dimensional Tolerance | Cutting Size | ±0.1 mm to ±0.2 mm | Higher precision achievable for t ≤ 3 mm. | ||||||
| Bend Position | ±0.3 mm to ±0.5 mm | Higher precision achievable for t ≤ 3 mm.Distance from bend line to edge or hole. | |||||||
| Hole Diameter | ±0.1 mm to ±0.2 mm | Recommended to use standard drill or laser sizes. | |||||||
| Material Thickness | As per material specification | Based on original material tolerance (e.g. ±0.02 mm for CRS, stainless steel).. | |||||||
| Overall Dimensions | ±0.5 mm (L ≤ 300 mm); ±1.0 mm (L > 300 mm) | Tolerance may vary with part size and structural complexity. | |||||||
| Orientation Tolerance | Orientation Tolerance | ±1° | Affected by material thickness and bending length. | ||||||
| Location Tolerance | Hole Position | ±0.2 mm to ±0.3 mm | Positional accuracy relative to edges or datum references. | ||||||
| Tapped Hole Position | ±0.1 mm | Total positional tolerance to be maintained within ±0.2 mm. | |||||||
*Please clearly indicate tolerances for nominal sizes below 0.5mm on your technical drawing.
