Summary         

• Aluminium roof expansion joints are specializedstructural profile systems used to bridge gaps inlarge roofs. They absorb thermal expansion andcontraction, wind loads, and seismic movementwhile maintaining a fully watertight seal usingdurable aluminium frames and flexible internalweather seals.

• Cutting / drilling / assembly  / waterproof testing

• Very high producing rate

• Professional team & exquisite workmanship

• Considerable after sale service

• Excellent dimension rate

• Very competitive price

Features 

Extruded Aluminium Frames: High-strengthaluminium alloy base members (typically 6000series) anchor securely to concrete hobs,timber curbs, or structural slabs..

Central Cover Plates: Sliding or floatingaluminium top plates protect underlyingmoisture barriers from UV rays, ice, snowloads, and foot traffic.

Waterproof Bellows/Gaskets: IntegratedEPDM, neoprene, or PVC moisture barriers tiedirectly into the roof's primary waterproofing membrane.

Seismic Centering Bars: Mechanicalassemblies that allow multi-directional shearand thermal movement without dislodging the covert.
