Why us

Why manufacturers switch to VSheat

Specialised in small parts

Focused on high-volume screws, nuts, bolts and springs — not large parts.

Everything under one roof

Heat treatment + Cr3+ zinc + phosphate + lab testing in one plant — fewer hand-offs.

Sample before full production

Confirm the spec with a trial lot to de-risk before a large order.
