Brief introduction to plastic steel door and window.

    Good air tightness: the experiment shows that the door and Windows of the plastic steel door are very good. In the buildings with air conditioning equipment, the ventilation air of the indoor and outdoor Spaces can be minimized.

    This gives full play to the efficiency of the air-conditioning system and saves energy.

    Good fire resistance: the profile of steel door and window is good fire material, not spontaneous combustion, can self-extinguish, use safety high.

    Good electrical insulation: the materials used in the doors and Windows of model steel are excellent electrical insulators. They are not conductive and have high safety.

    Thermal expansion is low: the line thermal expansion coefficient of window of model steel door is low, fireproof steel door is in winter summer two season temperature difference is very big, its shrinkage expansion coefficient is very small, do not affect model steel door window.

    Performance of the structure.

    Corrosion resistance: the aging resistance of steel doors and Windows is good, does not decay, does not rust, long-term use does not need maintenance.

    Good anti - theft property: plastic steel doors and Windows adopt fine hardware fittings, glass with soft and hard material pressure, good anti - theft.

    The appearance is exquisite: the profile of window of model steel door and manufacture USES the import equipment to process, its qualitative color inside and outside is consistent, the material is fine and smooth, processing dimensional accuracy is controlled by computer,

    Error is small.

    Weather resistant: plastic steel doors and Windows add a certain amount of advanced modification agent in the formulation, in the environment with strong climate change, the product will not go bad and become brittle. In the normal

    The service life can be up to 50 years.

    The sound insulation is good: the window of model steel door USES single layer glass sound insulation effect is 24db, use double layer glass sound insulation effect is 30db. Plastic steel doors and Windows sound insulation effect.

    Good thermal insulation, good insulation and energy saving: the energy consumption of doors and Windows of fire-resistant steel doors is only 24% of the steel Windows, and the thermal conductivity is only 1/1250 of aluminum. Summer indoor air conditioning and.

    Indoor heating is protected in winter.

    Water tightness is good: the water absorption rate of window of model steel is less than 0.1%, and have water hole, seal, water tightness is good.

    Impact resistance: steel doors and Windows adopt special formula and carefully designed profile structure, the product has certain impact strength.
