VT machining offers CNC Laser Cutting for A36 Steel (ASTM A36 / ~S275JR / Q235B), typically supplied hot-rolled. General structural plate; cheap and weldable, mill scale must be removed.
CNC Laser Cutting Notes for A36 Steel
Fibre-laser cutting of A36 Steel sheet gives a narrow kerf with minimal burr.
For estimating, a 100 × 100 × 10 mm block of A36 Steel weighs about 0.79 kg.

What is the typical lead time and minimum order for CNC Laser Cutting A36 Steel?
CNC Laser Cutting prototypes for A36 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 A36 Steel parts to my drawing?
Yes. A36 Steel cutting 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 tolerances can you hold for CNC Laser Cutting A36 Steel?
Achievable tolerances for A36 Steel cutting depend on the alloy, geometry and feature size. Laser cutting holds contour tolerances to around ±0.05 mm depending on thickness. Exact figures are confirmed against your drawing callouts.
Why is A36 Steel a good choice for CNC Laser Cutting?
A36 Steel is strong, economical and widely available, which makes it well suited to CNC Laser Cutting. We tune the process to the alloy so the finished A36 Steel cutting part meets your dimensional and functional requirements.
What surface finish is achievable on A36 Steel with CNC Laser Cutting?
Laser cutting leaves a clean cut face on A36 Steel with a small heat-affected zone; most parts need little secondary finishing.
What material thickness or size range suits CNC Laser Cutting A36 Steel?
Laser-cut A36 Steel thickness depends on the alloy and its reflectivity; we tune the fiber source and assist gas accordingly.
