Aluminum Plank, as the name suggests, is made of Aluminum Plank or Aluminum Plank alloy material. Or by the flat Aluminum Plank embryo by heating, rolling and straightening or solid solution aging heat and other processes made of plate Aluminum Plank products.
Aluminum Plank used in the building, including single-layer Aluminum Plank, composite Aluminum Plank and other materials, generally refers to the single-layer Aluminum Plank (also called a single Aluminum Plank or pure Aluminum Plank), used in architectural decoration works, in recent years in the Aluminum Plank curtain wall single-layer Aluminum Plank The more common. Aluminum Plank curtain wall is also a form of curtain wall, simply made of Aluminum Plank instead of glass made of curtain wall, Aluminum Plank wall is used for wall protection and non-lighting walls. Foreign Aluminum Plank curtain wall has been selected single-layer Aluminum Plank. Single-layer Aluminum Plank plate is generally made of pure Aluminum Plank. Aluminum Plank plate thickness of 3mm, in order to strengthen the Aluminum Plank plate surface strength, in the back of the Aluminum Plank plate, must be installed ribs (existing manufacturers uneasy), ribs made of thick Aluminum Plank, first with a flash welding machine to a screw cap Welded on the back of the Aluminum Plank plate and then put the ribs into the screws into the screws, fixed with screws. China in order to reduce the weight of Aluminum Plank, Aluminum Plank plate strength, we use Aluminum Plank alloy plate, often use No. 21 rust-proof Aluminum Plank code LF21 pressed Aluminum Plank plate for the curtain wall Aluminum Plank. Aluminum Plank thickness from the original 3mm reduced to 2.5mm, the strength of the alloy than pure Aluminum Plank about twice. Reinforcement with LF21 Aluminum Plank belt, the width of the Aluminum Plank plate thickness depends on the Aluminum Plank plate, generally thick 2-2.5mm, width 10-25mm. Aluminum Plank curtain wall of the back of the Aluminum Plank Why should the installation of stiffeners, is the case of positive and negative pressure in the outside, the Aluminum Plank plate will not be a depression, two will not bulge, so to avoid the Aluminum Plank wall and repeated vibration inside and outside the vibration sound. If you need insulation, can be inside the Aluminum Plank plate, placed rock wool, slag cotton or foam treatment. China's first production of Aluminum Plank curtain wall Aluminum Plank manufacturers, the production of Aluminum Plank plate width can reach 2.8 meters. Curtain wall Aluminum Plank surface treatment, can be divided into two methods, one is anodized, the other is electrostatic spraying. Anodized oxide film is generally more than 12μ, the color is only two kinds of bronze and white, color monotonous, more serious drawback is that each piece of Aluminum Plank plate surface color shades, many pieces of curtain wall panels together to form a curtain wall overall effect Very ugly. This shortcoming can be said that can not be eliminated, not the production technology, but because the Aluminum Plank plate is not a batch number, chemical composition, there are small differences, coupled with the electrolysis of the electrolyte current density and other factors can not be exactly the same, so After the oxidation of the number of colors are different, leaflets may not be obvious.
1. The hardness of Aluminum Plank.
Aluminum Plank hardness is too high, it is easy to break. This requires the choice of Aluminum Plank, mainly to see Aluminum Plank grades and status. General 1 series, 3 series, 5 series of more commonly used; 6 series, 7 series of hardness is too high, do first annealing to O state after the bend. There is the quality of Aluminum Plank, the same type of Aluminum Plank imports than the domestic material is not easy to crack, but the price of the material is also a lot of expensive.
2. Thickness of Aluminum Plank plate.
Too thick Aluminum Plank is not a good bend, we would like to understand, try to use a little thin Aluminum Plank.
3. Bend the size of the R corner.
Bending the greater the R angle, the higher the success rate, so try to adjust the larger corner R corner.
4. Aluminum Plank plate direction.
Bend direction should be perpendicular to the direction of Aluminum Plank plate lines, not parallel.
5. Need to pull the Aluminum Plank parts, in the case of the case is best to bend and then pull, otherwise it will increase the probability of bending fracture.
