C/Z Purlins & GirtsC/Z Purlins & Girts

C/Z Purlins & Girts — cold-formed thin-gauge C/Z sections roll-formed continuously; purlins can be designed as continuous lapped systems saving 10-15% steel; holes pre-punched.

Product Overview

Cold-formed thin-gauge C/Z sections roll-formed continuously; purlins can be designed as continuous lapped systems saving 10-15% steel; holes pre-punched. This product range suits a wide variety of applications; key features include pre-punched holes and continuous lapping. We re-verify parameters against your actual project conditions instead of applying standard specifications blindly — that's what prevents problems later on.

Specifications & Technical Parameters

Complete Compatible Systems

A single component rarely works in isolation. C/Z purlins & girts usually need to be engineered together with the primary structure, envelope system, connections and coating system to deliver overall performance. We supply structure and envelope as one integrated package, avoiding the blurred responsibilities of multi-vendor supply.

• Detailing & 3D ModelingTekla 3D modeling, member numbering and bolt lists — the factory schedules directly from the model, no rework
• FabricationIn-house cutting, assembly, welding, shot blasting and coating, with 6,500 t/month capacity
• Shipping & Customs ClearanceOversize transport plans, reinforced packing, export customs clearance and destination-port delivery documents
• Site InstallationTechnical teams available to supervise or fully contract the erection, incl. lifting plans
• Envelope & Cladding SystemRoof panels, wall panels, insulation, daylighting strips and ventilators supplied as one integrated package
• After-Sales & MaintenanceFree technical support during the warranty period, plus long-term maintenance manuals and spare-parts lists

Manufacturing & Quality Control

The factory runs CNC cutting, automated assembly, submerged-arc welding and shot-blasting lines with a monthly capacity of 6,500 t. Key processes (bevels, welds, coating thickness) are recorded and archived piece by piece; resident or third-party inspection can be arranged.

Delivery & Packaging

Standard delivery flow: drawing confirmation → production scheduling → factory inspection → reinforced packing (40HQ containers or break-bulk for export projects) → transport and handover. Member numbers match the packing list one-to-one, so crews erect by number and on-site checking time drops significantly.
