Construction
Cold-formed materials for connectors in buildings and steel structures. For applications such as beam-column connections, evaluate material options for bolts and screws, considering finished‑product grades, cold heading processes, and subsequent heat‑treatment requirements.
Materials for Bolts and Screws
When making inquiries, provide part drawings, wire diameters, and cold‑heading process details. The material’s delivery condition should be compatible with head forming and subsequent thread machining.
Indoor and Outdoor Installation
Specify the installation location of connectors and their coating requirements. Corrosion resistance is a joint consideration involving the material, heat treatment, and final surface finishing; it cannot be determined solely by the wire grade.
Finished‑Product Grades and Material Requirements
Clearly list the finished‑product strength grade, the subsequent heat‑treatment route, and the wire acceptance criteria, avoiding the mistake of equating finished‑product performance directly with the delivered wire’s properties.
Submitting Project Documentation
Provide part drawings, target wire diameter, delivery form, downstream processes, and inspection requirements to facilitate the definition of the sample scope.
