Cleanroom Doors, Windows and Interlock Systems
Seamless FRP Cleanroom Door
A fully molded fiberglass-reinforced plastic door leaf that encapsulates a closed-cell PIR core, eliminating exposed face seams in wet and chemical-cleaning environments.
- Seamless Molded FRP Skin
- Closed-Cell PIR Core
- Low-Moisture-Uptake Insulation
- Chemical-Resistant Hygienic Surface
Product Introduction
The Seamless FRP Cleanroom Door is produced in a closed mold so the glass-fiber-reinforced polyester wraps continuously around the leaf faces and edges. A high-density closed-cell PIR insulation layer supports the shell, and embedded aluminum reinforcement accepts hinges, locks and protective hardware. Because there are no folded metal seams on the exposed leaf, the surface is well suited to repeated washdown and cleaning chemistry that can attack painted edges.
Key Features
FRP does not develop red rust when the surface is scratched.
Closed-cell PIR limits internal moisture uptake and keeps the leaf dimensionally stable.
Embedded reinforcement provides secure anchorage for hardware without exposed plates.
Smooth gel-coat can be repaired locally if deep impact damage occurs.
Customer Product Concerns
FRP doors are selected when moisture and chemicals expose the weaknesses of folded metal skins, porous cores and coating-dependent corrosion protection.
Cleaning liquid penetrates folded seams and damages the internal door core.A continuously molded FRP shell encapsulates the core across faces and edges.
Scratched steel requires prompt coating repair to prevent rust.Fiberglass composite remains non-ferrous through the full skin thickness.
Moisture-sensitive cores can swell and distort door alignment.The low-water-uptake closed-cell PIR core is fully encapsulated by the molded FRP shell.
Surface-mounted reinforcement introduces difficult cleaning edges.Aluminum hardware blocks are molded inside the leaf at factory-defined fixing zones.
Typical Applications
Biotechnology washdown roomsPharmaceutical wet-process areasFood manufacturing hygiene zonesBattery production clean spacesCorrosive laboratory environments
