Product Description:

1. Pre-Painted Galvanized/Aluzinc Steel Roof Description

With GI as base material, after pretreatment (degrease and chemical treatment ) and liquid dope with several layers of color, then after firing and cooling, finally the plate steel is called pre-painted galvanized (aluzinc) steel. Pre-painted galvanized roof is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance.

Q:What does "steel roll number" mean?
For the future production, improve production efficiency, reduce operating costs.
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
Cold rolled steel coils are generally sprayed antirust oil, according to user requirements, light, medium, heavy oil 3 types. Nevertheless, if the oil is volatile or in a humid environment, the steel plate comes into contact with the water for a period of time, indicating that it is beginning to rust.
Q:How can the outer diameter and weight of steel coil be converted?
Of course, the calculation is relatively coarse, and the volume has a lot to do with the tension.
Q:The difference between aluminized color steel roll and ordinary color steel roll
Aluminized color coated sheet is a new type of material produced in China in recent years due to its high end applications. It is often used as an indication of CCLI. It is made of galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon), which is more galvanized and more corrosion resistant. It is processed by surface degreasing, phosphating and complexing treatment, and is coated with organic coating.
Q:The strip tower height
Defects: cold-rolled steel sheet (coil)
Q:How are steel tape measures installed?
The spring piece is fixed on the shaft, the other end is connected with the measuring tape core, fixed tape shell with a shaft, the spring plate and a circle around the axis of the ruler core, wrapped after the ruler core extends from the outer end of the incision length of the shell, gently pull, the spring is tightened, the pull out the part from the incision and then removed around the shaft, then gently pull out, and then put the ruler core tied to the shaft, removed from the incision so repeatedly, until the spring to put all the ruler core recovery. Then a cotter pin on the central shaft installed on the lid, will tighten the screws.
Q:A roll of 1 meters wide color steel roll about how many tons?
In general, between 3.5 and 5 tons. Our company uses 0.17*1000 white color steel roll. The weight is usually around 4.5 tons. Different manufacturers will have different sealing rolls.
Q:Where are the coils and the steel plates used? Where did the steel plate come from?
The use of steel coils, refrigerators, washing machines, household appliances, and other industries, parcels are winding.Steel plates can also be found everywhere: airplanes, guns, trains, ships, space shuttles, spaceships, automobiles, etc..Steel plate through mining - sintering - iron smelting - smelting - forming.
Q:On how to reinforce steel coils in a container
The inside of the container is rectangular, four angles with hook, so can the packing time for warehouse experienced workers in the upstairs said, with the steel wire rope and steel reinforcement will lock up, if the mud coil is hollow, the wire rope through the middle and then cross to get on fixed on the four corners, and on the floor on the wooden wedge nail to prevent steel coil rolling.
Q:Why can hot rolled coils be placed outside?
Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
