WS concealed-fix clip-lock roof sheets (Cliplock)

Concealed fixing without seaming

Clip-lock sheets are fixed by snapping the ribs over concealed clips screwed to the purlins. There are no fasteners through the sheet and no seaming machine is needed – a clean roof that installs quickly.

The high-tensile G550 substrate gives stiffness at thin gauges. Middle and side clips (CT-1 / CT-2 positions) hold every rib.

WS clip-lock roof profiles — WS Cliplock profiles – cover width and rib height in mm.

Profiles and technical data

WS clip-lock roof sheets
Code	Cover (mm)	Coil width (mm)	Rib (mm)	Thickness (mm)	Yield	Use
WS 1000-40-4	1000	1200	39	0.45–0.60	G550	Roof
WS 970-41-4	970	1200	41	0.45–0.60	G550	Roof
WS 945-41-4	945	1200	41	0.45–0.60	G550	Roof

Good practice

Lay sheets in the direction away from prevailing weather
Check clip alignment every few purlins
Engage the ribs fully along the whole length before walking on the sheet
Use matching clips for each profile

In cyclonic regions, concealed-fix roofs must be tested and installed to the applicable cyclonic test and installation requirements.

자주 묻는 질문

What is the difference between clip-lock and standing seam?

Clip-lock sheets snap onto clips and need no seaming; standing seam sheets are seamed together on site and allow more thermal movement on very long sheets.

Why is G550 steel used?

High-tensile G550 steel gives the stiffness the profile needs at 0.45–0.60 mm thickness.
