VT machining offers CNC Wire EDM 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 Wire EDM Notes for SGCC Steel
Wire EDM cuts SGCC Steel with fine detail and sharp internal corners down to the wire radius.

Request a QuoteFrequently Asked Questions
How clean are the edges produced by CNC Wire EDM on SGCC Steel?
Machined SGCC Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What tolerances can you hold for CNC Wire EDM SGCC Steel?
Achievable tolerances for SGCC Steel EDM machining depend on the alloy, geometry and feature size. EDM holds tolerances to around ±0.002 mm with no cutting force on the part. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom SGCC Steel parts to my drawing?
Yes. SGCC Steel EDM machining 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.
Can you EDM-machine hardened SGCC Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult SGCC Steel can be machined to fine detail and tight tolerance without distortion.
Why is SGCC Steel a good choice for CNC Wire EDM?
SGCC Steel is strong, economical and widely available, which makes it well suited to CNC Wire EDM. We tune the process to the alloy so the finished SGCC Steel EDM machining part meets your dimensional and functional requirements.
