Steel Processing Capabilities
You can buy steel from us as a raw coil, or as a part that is ready to install. Between those two points, we run 12 processing steps in our own plant. This page lists each process, the products it applies to, and what to send us for a quote. Processing here usually costs you less than cutting at destination. You ship only usable material, and you skip one round of local handling.

Coating Processes
Hot-Dip Galvanizing
Hot-dip galvanizing dips steel in molten zinc to protect it from rust. We run a large continuous galvanizing line for coil.
Applies to: galvanized steel coil, sheet
Base metal: DX51D+Z,DX52D+Z, DX53D+Z, DX54D+Z, S250GD+Z, S350GD+Z, S450GD+Z, S550GD+Z
Thickness: 0.09-3.0 mm (typical), 4.0 - 6.0 mm (max)
Width: 1000, 1219, 1250, 1500 mm (max)
Zinc coating: Z40–Z275 (typical), Z600 (max)
Spangle: regular / minimized / zero
Standards: ASTM A653, EN 10346, JIS G3302, GB/T 2518-2019, AS 1397
Capacity: 20,000 tons/month
Choose the zinc weight by the site, not by the price. For coastal or humid use, go to Z180 or above. For indoor framing, Z60–Z80 is usually enough.
To quote, send: base grade, thickness × width (or pipe size), zinc weight, spangle, quantity.
Color Coating (PPGI / PPGL)
Our color coating line paints galvanized or galvalume coil with a primer and a top coat. The result is PPGI for roofing, wall cladding and appliances.
Applies to: PPGI coil and PPGI sheet
Substrate: galvanized / galvalume, Z or AZ
Paint systems: PE, SMP, HDP, PVDF, PU etc.
Colors & Patterns: RAL color codes, custom colors, matte / glossy / embossed textures available
Line capacity: 15,000 tons/month
PE is fine for most inland roofing. For strong sun or coastal air, ask about HDP or PVDF before you pick the color.
To quote, send: requied weight, thickness × width, paint system, RAL color, coating, quantity.
Coil Processing
Cut to Length
Cut to length uncoils a coil, levels it flat, and shears it into sheets. You get flat sheets in your exact length.
Applies to: stainless steel coil, galvanized steel sheet, PPGI and carbon steel coil
Thickness: 0.25–16 mm standard; up to 20 mm, confirmed per order
Width: 300–2000 mm
Length: 2000–6000 mm (typical); shortest 500–700 mm
Length tolerance:± 2～3 mm
Flatness: 5–7 mm/m
Protective film: PVC / laser film on request
For polished or brushed stainless, ask for film before cutting. Adding it after cutting leaves edge marks.
To quote, send: grade, surface, thickness × width, sheet length, pieces or tons.

Slitting
Slitting runs a wide coil through rotary knives to make narrow strips. It is how we supply strip in non-standard widths.
Applies to: stainless steel strip, galvanized and carbon steel coil
Thickness: up to 14 mm standard, 16 mm on request
Min. strip width: 20 mm
Width tolerance: according to thickness
Edge: mill edge / slit edge
Please specify your required unwinding direction so we can prepare the coils to suit your feeding equipment.
To quote, send: grade, thickness, slit width, inner diameter, coil weight, quantity.

Recoiling (Coil Splitting)
Recoiling splits one heavy master coil into smaller coils. Use it when your decoiler or crane can't handle a full mill coil.
Applies to: stainless, galvanized and PPGI coil; strip
Coil weight after split: down to a few hundred kg for thin gauges; heavy gauges confirmed per order
Inner diameter: 508 / 610 mm
Thickness range: 0.25–16 mm (up to 20 mm on request)
Tell us your crane limit and decoiler ID. We split to fit, so you don't unload more than you can lift.
To quote, send: grade, size, target coil weight, ID, quantity.

Laser Cutting — Sheet & Plate
Fiber laser cutting cuts flat parts straight from your drawing. It suits small batches, complex shapes and tight hole patterns.
Applies to: stainless steel sheet, stainless steel plate, carbon and galvanized sheet
Laser power: 6 kW
Max. thickness: stainless 10 mm, carbon 18 mm
Bed size: 6000 × 2000 mm
Tolerance: according to thickness
File formats: DXF, DWG, STEP
For stainless above 2 mm, nitrogen-cut edges stay clean and ready to weld. Ask for it if the part will be visible.
To quote, send: drawing file, grade, thickness, surface, quantity per part.

Laser Cutting — Pipe & Tube
Tube laser cutting cuts lengths, holes, slots and miters in one pass. It replaces sawing plus drilling for most frame parts.
Applies to: stainless steel pipe & tube, stainless steel square pipe & tube, galvanized and carbon tube
Shapes: round, square, rectangular, hexagon
Size range: OD 10 – 350 mm
Max. wall: 10 mm
Max. tube length: 9 m
Tolerance: ±0.15 mm
Send a 3D model if your tube has notches or angled ends. A flat drawing often misses the cut angle.
To quote, send: 3D file or drawing, grade, tube size × wall, quantity.

Bending
CNC press brakes form sheet and plate into angles, channels and boxes.
Applies to: stainless, carbon, galvanized and PPGI sheet and plate
Press brakes: 4 units, 160 t, 3200 mm bending length
Thickness: up to 10 mm, depending on bending length
Angle tolerance: ± 0.5°
Brushed or mirror stainless needs film-protected bending. Ask for it, or the die can mark the face.
To quote, send: drawing with inner radius, grade, thickness, surface, quantity.

Welding
We weld cut and bent parts into enclosures, boxes, frames, brackets and assemblies.
Applies to: stainless, carbon steel sheet, plate and tube
Methods: TIG, MIG
Welder qualification: ISO 9606-1 (steel/stainless), ISO 9606-2 (aluminum)
Weld finishing: Weld finishing: grinding, pickling and passivation
For stainless parts in food or wet areas, ask for pickling after welding. It removes heat tint that can rust.
To quote, send: assembly drawing, grade, weld type, finish requirement, quantity.

CNC Machining
CNC lathes and machining centers turn, mill, drill and thread parts from bar, plate or tube.
Applies to: stainless steel rod, carbon steel bar, plate and tube
Machines: 1 CNC lathes, 4 machining centers
Max. turning diameter: 500 mm
Tolerance: ± 0.02 mm
To quote, send: drawing with tolerances, grade, quantity, surface finish.
Request a QuoteSurface Finishing
Brushed / Hairline Finish
Brushing runs abrasive belts over stainless to create a fine, even grain. It hides fingerprints and small scratches.
Applies to: stainless sheet, coil and pipe & tube
Finishes: No.4, HL (hairline), satin
Grit: 180 – 320
Max. width: 2000 mm
Film: PVC / laser film
For elevator panels and kitchen work, HL looks cleaner than No.4. No.4 is easier to match on site repairs.
To quote, send: grade, size, finish (No.4 or HL), film, quantity.
