Fiberglass/FRP/GRP doors are constructed using normal 2mm or 2.5mm high strength thick Fiberglass SMC woodgrain skins permanently bonded to a perimeter sub-frame of synthetic material and filled with an insulating polyurethane core. The rigid polyurethane foam core is CFC and HCFC free, has an ozone depletion potential (ODP) of zero and a global warming potential (GWP) of less than five. The synthetic material of the sub-frame can be worked in a similar way to timber. 

Fiberglass/FRP/ GRP doors can be trimmed in width and cut down in height, allowing doors to be sized to fit existing openings for refurbishment projects. The slab construction provides a fully sealed product impervious to moisture.

Advantage of our Fiberglass / Glassfiber /FRP/GRP composites door:

Characteristics of Wood Texture: A Comfortable Feeling

The wooden texture of every door feels natural. Our wooden textured doors offer greater warmth to the touch than the icy surface of a conventional steel security door.


Waterproof and Mothproof

Our doors are made from corrosion-resistant materials which are not only waterproof, but they are also resistant to microorganism which may invade your property, which makes our doors particularly suitable for use in rainy, high humid, and coastal area, or where other corrosive substances may exist.

Superior Resistance to Warping and Corrosion

Our doors are built to last no matter the weather; they meet or exceed international testing standings for warping and corrosion. No failures, distresses or deformations were reported by Air-Ins Inc. Laboratory in a Thermal Cycling Slab Bending Test on our panel doors. Our doors meet the standards of OnSpeX Toronto which conducts warping tests by submitting doors to extreme temperatures ranging form -40C to +30C and tests for warping. The resistance of our doors to deformation and corrosion is further verified by British agent. Please contact us for more professional international testing report results.


Hand-Painted Natural Color

Every door is produced with a complex process involving hand-painting and hand-polishing. Colors appear natural as do the textures of the wood textured doors. Negative pressure spray techniques create smooth surfaces free of imperfections. Our doors are allowed to dry naturally rather than being dried at high temperatures.



Our products are produced with the environment in mind. The SGS Testing Service verified. Our doors are free form chlorofluorocarbons and other ozone-depleting substances, and our painting does not contain the Lead (heavy metal).

 Peace and Quite

Our doors provide a quite and private environment for your home through their excellent noise insulation (the ASTE 90 Sound Transmission Loss Test Report form Architectural Testing determined a filler wall which achieved a STC rating, in accordance with ASTM 413,of 67).

Superior Anti-Theft Performance

Our doors are designed with your security in mind. They have been subjected to Chilt/P12005/01/Rev1 testing form Chiltern Dynamics according to three international standards: PAS 23-1:1999,PAS 24-1:2007+A1:2009 Enhanced security performance requirements for door assemblies and BS 6375 Part 1:2009 Performance of windows and doors-Part 1.Detailed test results available upon request.

Excellent Fire Resistance (Fire Resistant Series)


Our products have excellent fire resistance according to the WF Test Report form Exova Warringtonfire.Our doors excelled when tested in accordance with BS EN 1634-1:2008, exceeding the standards for fire resistance.
