Aluminum alloy profiles

    Door frames, tracks and outer handles are using high-grade alumina alloy, from 8 m aluminum rods extrusion molding. Advantages are beautiful, corrosion-resistant, never rust, greatly improving the service life of industrial doors. Ordinary iron galvanized U-shaped slot side of the service life is about 5 years, aluminum side life is up to 15 - 20 years.

Lower rail structure

We use a specially designed with a guide groove of the aluminum alloy frames and guide wheel using nylon material with a beautiful appearance, durable, easy installation, sliding fast, practical.

Wheels structure

The structure has a fixed wheel frame, eccentric shaft, hanging wheel, fasteners and other components. Wheel frames are fixed with galvanized iron pieces, high strength, no deformation, wheel with nylon wheel, rather than composite plastic, with good mechanical properties and wear resistance, and no noise.

Wheels and guide pulleys are nylon material

1. High mechanical strength, good toughness, a higher tensile, compressive strength. Specific tensile strength than metal, tensile strength close to the yield strength, more than twice as high as ABS. On the impact, stress absorption of strong absorption.

2. Fatigue resistance performance, repeated by repeated inflection can still maintain the original mechanical strength.

3.Softening point high, heat, can be used at 150 degrees for a long time.

4.Smooth surface, small friction coefficient, wear, as a transmission part of its long service life.

5.Corrosion-resistant, very alkali and most of the salt, but also resistant to weak acid, oil, gasoline, aromatic compounds and general solvents.

6. Self-extinguishing, non-toxic, odorless, good weather resistance, inert to the biological erosion, a good antibacterial, anti-mildew ability.

7. It has excellent electrical performance. Electrical insulation is good, even in high humidity environment still has good electrical insulation.
