For special places (such as need to be suspended, or in places with high corrosion or rust corrosion), it is recommended to choose alloy series, and the thickness is not less than 6.0mm. This series and non-slip aluminum plate of thickness can guarantee the safety of staff to the maximum extent and the service life of non-slip aluminum plate.

See with makings, the aluminium profile that high grade aluminium alloy prevents skateboard to use, thickness, intensity and oxidation film are used, should accord with the relevant standard regulation of country, wall thickness should be in 1.2 millimeter above, tensile strength should achieve every square metre 157 Newton, yield strength should achieve every square millimeter 108 Newton, oxide film thickness should achieve 10 micron. If do not reach above standard, it is inferior aluminium alloy door window, cannot use.

Second look at the processing, high quality aluminum alloy skateboard, fine processing, exquisite installation, good sealing performance, free switch. Inferior aluminium alloy door, choose aluminous profile series and norms blindly, processed and manufactured in order to curium cut replaces mill processing, not according to the requirements for installation, sealed performance is poor, switch does not freely, not only rain of air leak leakage and occurrence glass blast crack phenomenon, and encounter blast and outside force, blow push-pull part or glass easily fall or touch fall, destroy content cuts.

See price 3, below general circumstance, high grade aluminium alloy prevents skateboard because of production cost is high, price is inferior aluminium alloy defends skateboard to want to be high 30% or so. At present, there are many individual clients who process aluminum alloy skateboard. They do not know the structural features and performance of aluminum alloy skateboard. In order to reduce the cost of jerry-cut materials, shoddy, the hidden dangers of products larger, generally should not be used. Had better choose normal aluminium alloy to defend the product of manufacturer of skateboard manufacturer.
