Product Description:

1.Corrugated Roofing Sheet Features:

. A strong anti-corrosion properties, good corrosion resistance. The use of hot dipped galvanized steel substrates for the Color Painted steel coil, with the exception of zinc have anti-corrosion layer, a layer of coatings have seized coverage and protection,  allowing effective anti-rust products, galvanized coil about life than double.

. A good cold-formed molding processing, users can directly processed into finished products. Substituting wood to steel, easy to transport, and efficient construction, energy conservation.


2.Applications Corrugated Roofing Sheet:

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:What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
General handling steel rolls are used for driving. Forklift trucks are OK, but a larger fork truck, usually cold rolled, weighs less than 15T. The hot rolled coil is below 30T.
Q:What's the difference between hot rolled coil and hot-rolled carbon thin steel coil?
Hot rolled coil is used for continuous casting slab or as raw material, after reheating furnace heating, descaling into the roughing mill of high pressure water, roughing material by cutting head, tail, and then enter the finishing mill, the implementation of the computer controlled rolling, after finishing through the laminar cooling (computer controlled cooling rate and coiling) reel, a straight hair volume. Hair straightenerrollhead, tail tongue shapeand thefishtail shape, thickness, width of poor accuracy, edgehaswavy, folding, tower and other defects. The volume is heavy. (general management industry likes to use. )
Q:What brand steel tapes are of good quality?
Personal feeling is also good for the Great Wall Seiko tape, upstairs several estimates are the production of steel tape manufacturers, of course, that their goods well. Our unit now buy all the Great Wall Seiko goods, said the tape is good, not because it is so durable
Q:On how to reinforce steel coils in a container
In the bottom and sides with a thick strip stuck, but also to ensure that the wood will not loosen down...... Rough steel rolls, I saw people loading and unloading on the docks, poked them directly with a small forklift truck, and then reinforced with wooden planks
Q:Why can't the coil weight be too low?
Because the steel coil is stored in warehouse stacking level, if the coil weight is too low, resulting in a single coil capacity is reduced, so that the steel roll easily crushed and deformed;
Q:Can cold rolled galvanized steel coils be acid washed after oxidation?
If it has been galvanized, it can not be pickled, and if it is pickled, it may corrode the zinc layer
Q:Where do I need hot galvanized steel coils and color coated rolls?
In industrial or coastal areas, due to the influence of sulphur dioxide or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, the coating has been soaked by rain for a long time, or the temperature is too large and easy to dew. It will be corroded quickly and the service life will be reduced. A building or building made of colored coated steel plates, often with a long service life when washed by rainwater, otherwise affected by sulfur dioxide, gas, salt, and dust. Therefore, in the design, if the roof slope is greater, the more difficult to accumulate dust and other dirt, the longer the service life; for those areas or parts that are not often washed by rain water, should be regularly washed with water.
Q:What is the difference between cold rolled strip and cold rolled steel coil?
Single literal explanation, volume and band are different, appearance shape is not the same.
Q:Is a steel plate the same as a steel coil?
Generally speaking, they can be used interchangeably, and the purchase price of the plate is slightly cheaper.
