VT machining offers CNC Bending for Q235 Steel (GB/T 700 / ~S235JR / ~A36), typically supplied hot-rolled. Chinese standard structural steel, yield ≥235 MPa.
CNC Bending Notes for Q235 Steel
Q235 Steel bends to a tight inside radius (about 1× thickness) in this condition.
For estimating, a 100 × 100 × 10 mm block of Q235 Steel weighs about 0.79 kg.

Why is Q235 Steel a good choice for CNC Bending?
Q235 Steel is strong, economical and widely available, which makes it well suited to CNC Bending. We tune the process to the alloy so the finished Q235 Steel forming part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Bending Q235 Steel?
Achievable tolerances for Q235 Steel forming depend on the alloy, geometry and feature size. We hold tight, repeatable tolerances appropriate to the feature and material. Exact figures are confirmed against your drawing callouts.
What material thickness or size range suits CNC Bending Q235 Steel?
We form Q235 Steel sheet and plate to your developed flat pattern and bend sequence.
Does CNC Bending Q235 Steel require dedicated tooling?
Most Q235 Steel forming work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What surface finish is achievable on Q235 Steel with CNC Bending?
Surface finish on Q235 Steel is controlled to your specification; we confirm the achievable Ra against your callout.
