VT machining offers CNC Bending for SGCC Steel (JIS G3302 hot-dip galvanised), typically supplied cold-rolled, HDG coated. Thicker hot-dip zinc than SECC for outdoor corrosion protection.
CNC Bending Notes for SGCC Steel
SGCC Steel bends to a tight inside radius (about 1× thickness) in this condition.
For estimating, a 100 × 100 × 10 mm block of SGCC Steel weighs about 0.79 kg.
Process Data for CNC Bending SGCC Steel
| Minimum inside bend radius | ~0.5 × t (across the grain) |
|---|---|
| Press force, 2 mm sheet, V16 die | ~9.8 t per metre |
| Typical springback at 90° | 0.5-1° |
| Angle tolerance | ±0.5° (CNC back-gauge, angle measurement on first part) |
Typical values for SGCC Steel, Cold-rolled, HDG coated; confirmed on the first part.

What is the typical lead time and minimum order for CNC Bending SGCC Steel?
CNC Bending prototypes for SGCC Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Can VT machining make custom SGCC Steel parts to my drawing?
Yes. SGCC Steel forming is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What material thickness or size range suits CNC Bending SGCC Steel?
We form SGCC Steel sheet and plate to your developed flat pattern and bend sequence.
Does CNC Bending SGCC Steel require dedicated tooling?
Most SGCC Steel forming work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
