Processing Guide

Shipbuilding steel plates require proper fabrication methods to maintain mechanical properties and meet marine construction requirements.

Cutting

Plasma cutting, flame cutting and other precision cutting methods are commonly used according to plate thickness and project requirements. Proper heat control helps maintain dimensional accuracy.

Welding

Suitable welding procedures, approved consumables and controlled heat input are recommended to ensure weld quality and structural reliability.

Surface Preparation

Shot blasting and surface cleaning are commonly used before coating to improve paint adhesion and enhance corrosion protection.

Forming & Machining

Bending, forming and machining parameters should be selected according to steel grade and thickness to avoid deformation and maintain material performance.
