FAQ
MOQ and lead time?
Sourced per order or made to drawing. MOQ and lead time are confirmed at quote time by quantity, material and finish. Other sizes in this family are listed above; unlisted specs can be sourced to your drawing.
Can material or grade be substituted?
Current grade: 304 austenitic stainless, Rm≥700 MPa, general corrosion resistance. Swapping grade/material changes strength and corrosion resistance (e.g. 8.8→10.9 raises strength, 304→316 raises chloride resistance), re-check design load and environment before substitution.
How do I choose the finish?
Plain / no coating: indoor dry environments. Other finishes (HDG, Dacromet, electro zinc) can be quoted on the same size.
