Objects can be classified on the basis of material used for manufacturing. Engineered materials that are made up of more than one material of desired chemical and physical property are called composite material.

Composite mainly comprises of materials that can be classified as matrix and reinforce. The matrix material supports reinforce whereas reinforce material forms the structure an impart strength. Composite materials generally have high strength to weight ratio, this quality helps for applications where high strength is required at less weight. The most common examples of composite material are fibreglass, carbon fiber, plywood etc. Fibreglass is made from fine glass fiber which acts as reinforcement material to polymers which act as matrix. Similarly GRP (Glass reinforced plastic) material is also used for manufacturing of doors.

According to the properties of GRP they render high strength, glossy effect due to glass though light in weight due to plastic. GRP doors also known as composite doors have high strength to weight ratio this makes it for the best choice for entrance doors which needs looks and security equally. GRP has all the desired property for an entrance door such as

• Resistant to heat and water

• No colour fading in sunlight

• No expansion or warping due to moisture

• No need to paint

• As non conductor of heat so by structure it is energy efficient

• Stronger in strength than wood though lighter than it

There is also other material doors offer uPVC, PVC, PVCu.

These clear advantages make it a perfect choice for entrance door with style.
