Quality control is built around traceable material checks, production inspection, dimensional review, packing confirmation and project communication. The goal is simple: reduce site risk before the cargo leaves the factory.
Inspection focus by product system
- Steel structures: steel grade, cutting, welding, hole position, anti-corrosion treatment and component marking.
- Sandwich panels: panel thickness, core material, color, surface finish, edge condition, length tolerance and packing protection.
- Cold room and clean room systems: panel joint details, door and window matching, sealing accessories and project-specific material lists.
- Modular and container houses: frame assembly, wall and roof panel condition, openings, accessories and pre-shipment visual check.
Why this matters for overseas buyers
International projects lose time when drawings, quantities or packing are unclear. HIH Steel keeps quality records and shipping photos so the buyer can check material scope before customs clearance and site installation.
