Product Features

- Complete automation options (chain, belt or screw openers), obstacle sensors and safety edges for secure, smooth operation.

Product Value

These doors deliver measurable value through enhanced security (multi‑point/biometric locking and anti‑theft hardware), convenience (automatic openers and remote access), energy savings and comfort (thermal insulation and sound attenuation), and safety (fire‑retardant cores and safety sensors). As a wholesale offering from GP Global, they provide scalable, customizable solutions with professional design support and after‑sales service—reducing procurement complexity for builders, installers and resellers.
