Aluminum magnesium manganese plate (standing seam) wind load: good standing seam roof under the stress bar to all metal roof panel systems. Because of its special fixing method, the stress concentration in the nail hole caused by repeated positive and negative wind pressure is avoided when the general screw fixing system encounters a strong wind. It has been proved by experiments that the specimens in the repeated loading test of 7kPa are not damaged. In the system, the single rib single point is still in elastic deformation under the simulated concentrated wind load of 1.5kN, and no damage occurs.

Aluminum magnesium manganese plate (standing seam) corrosion and durability: metal roof panels are aluminium magnesium manganese alloy plate and aluminium zinc plate two, two have excellent corrosion resistance. The aluminum magnesium manganese plate has the characteristics of light weight and high strength, and has better corrosion resistance and durability than ordinary aluminum alloy, especially in acid environment. After certification by the authorities, the roof panel made of this material has a service life of more than 40 years under normal circumstances. In addition to the panel, from other materials to accessories and screws with anti-corrosion ability such as turbidity, ST Aluminum Alloy holderup with hard plastic insulation insulation pad, isolation and the lower part of the steel plate or aluminum (c/z type steel purlin), so as to avoid galvanic corrosion; fasteners used imported stainless steel screws and waterproof aluminum the use of rivets, roof not because of a weak influence. The service life of aluminized steel plate can reach four times more than that of ordinary galvanized steel plate.
