Andewa is based on flame-retardant unsaturated polyester resin,with alkali-free glass fiber chopped strand mat as reinforcing material,plus weather-resistant polyester felt and weathering fluorocarbon layer.After the most advanced composite material pultrusion in China.The technology is produced with a tensile force,high temperature and high pressure of 80KN(ton).The product design is reasonable,solves the problem that the ordinary composite material is not resistant to aging,poor compactness,unstable geometric size and low fireproof grade;solves the problem that the metal tile is not resistant to corrosion;and solves the problem that the synthetic resin is not resistant to hail impact.

◆Super weather resistance

The double weathering protection of fluorocarbon coating and polyester felt ensures the service life of Andeva.Even if exposed to ultraviolet light,heat,cold,moisture,or corrosive environment for a long time,it can maintain the stability of the product and ensure the long-term safe use of the product.National Chemical Building Materials Testing Center 10,000 hours weathering test?E=4.18,laboratory 10,000 hours,equivalent to 28 years in nature.)

◆Excellent corrosion resistance

The Andhra raw materials themselves are corrosion resistant.Andeva was soaked in 15%hydrochloric acid,20%sulfuric acid,40%hydrofluoric acid,15%hydrofluoric acid,20%phosphoric acid,20%nitric acid,5%sodium hydroxide,ammonia aqueous solution for 120 hours.Variety.

◆The geometry is stable,not deformed,and has good high temperature resistance.

The production temperature of Andeva is 180C.The thermal deformation temperature of Andwa is higher than 250C;the thermal expansion coefficient of Andeva is 1.95X10-5C-1,and there is no deformation of the waist during use.

◆High resistance to hail impact

Andeva uses the alkali-free glass fiber short felt as a reinforcing material,and it will not break when it encounters hail within 50mm.A 1kg steel ball will fall freely at a distance of 3m from Antewa.

◆Excellent load resistance

Antwa uses advanced pultrusion technology for higher mechanical strength and physical properties.

◆strong wind resistance

Andeva itself is dense and tough,and the special accessories are designed reasonably.It can carry 2000PO wind pressure.(equivalent to 8-10 wind)
