☆ Excellent weather resistance performance:
The thermal expansion and contraction sliding technology of roof makes it suitable for various types of roof system;
☆ Outstanding water and air tightness:
With the help of Pittsburgh lock seam technology, the roof panels are connected by a lock seam,which are truly achieve a 360° + 135° upright lock seam. The maximum lock seam angle can reach 540°. Under this lock seam,it improves watertight and airtight performance.
☆ Achieve thermal stress relief of the entire roof:
The concealed sliding bracket is fixed on the structural system, this makes the installed roof can realize the overall sliding and release the thermal expansion and contraction internal stress. Finally, it can avoid the damage of the roof panel during the reciprocating cycle displacement.
☆ Strong wind resistance:
After the roof panel and the bracket lock seam are engaged, a strong connection is formed between the roof panel, the brackets and the purlins. The roof load is transmitted without obstacles,which is ensuring the wind resistance of the entire roof.
☆ Perfect alignment and installation:
Factory-punched panels and structural members assure proper alignment and accurate installation.
