Product Description:

Galvanized steel strips are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 –180 grams per square metre.

Hotdip galvanized steel strips are produced by immersing steel in a zinc bath. An appropriate galvanizing process requires a pretreatment process during which the steel passes through different baths which prepare the surface for zinc coating. In this stage, chemicals are used to clean the surface of the steel. After the chemical treatment, the steel coils pass through a bath of melted zinc at temperatures around 460 ° C. The resulting uniform coating is finished through a process of skin-passing to provide smooth and shiny appearance of the finished product. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customers demand.

Technical specification :

Steel grade: DX51D+ZZinc coverage:30-180 g/sqm on both sides (depending by the requested specification);Thickness: between 0,2 mm and 1,00 mm;Width:600mm,914mm,1000mm, 1220mm and 1250 mm;Coil weight: 4-6 mt;Coil ID: 508 mm;Coil OD: 900-1500 mm ;

Depending on their usage, the hot-dip galvanized coil can be delivered slightly oiled.

Q:Hot rolled strip, the theory of the thinnest, how thin rolling, why not rolling too thin, is the material or the reasons for plate shape?
Thinning is related to width. But after a certain width, the amount of thinning has little to do with the width. The theory of hot rolling can be rolled to 0.8mm, and in practice, the 1.2mm is virtually useless.
Q:What's the reason for the strip after pickling?
Pickling is only surface rust removal, which will not affect the hardness of the material.
Q:What is the difference between steel strip and strip steel?
The difference is: the strip, that is used for processing into steel belt materials, iron and steel enterprise is produced by hot rolling cold rolling plate, a large volume of.
Q:What's the difference between strip 235 and 235b?
235B only requires a temperature environment of 20 degrees C; this is because of their chemical composition of sulfur, S, phosphorus, P content indicators caused by different.The 235 is 235A, 235 in the material according to the sulfur phosphorus content from high to low is divided into ABCD four grades, grade a sulfur phosphorus was the highest relative performance (welding, plasticity) is the worst, D performance is the highest, the lowest content of parathion.
Q:Is the strip steel strip?
Including strip steel, generally speaking, the strip refers to the plate and strip of the general term, but the plate in the middle part of the plate and the delivery of sheet metal is cut from the strip.
Q:1 can thick galvanized steel square pipe burn welding?
Galvanized square is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency; or the cold hollow steel well in advance of the re galvanized square by galvanizing processing of pipe.
Q:What are the high speed steel strips and material specifications?
High precision (H) and wide and high thickness accuracy (KH) four kinds of strip steel. According to the material condition, two kinds of strip can be divided into chilled and annealed, the former has higher strength and the latter has good plasticity and toughness.
Q:Where is the lining board made of polyurethane lining? Please contact immediately
The flame retardant and antistatic performance, has direct relationship with the selection of additives in the domestic production and sales of all kinds of additives manufacturers and enterprises thousands, but those additives in line with our formulation requires, for internal performance we use without affecting the polyurethane? Pengbosheng company has done numerous tests, try hundreds of flame retardant in different and antistatic agent, screened from for our formulation system of auxiliaries. Selecting the proper amount of additive can not only give full play to the performance of the assistant, but also achieve the design indexes of flame retardance and antistatic, and can not lose the superior performance of polyurethane.
Q:Hot rolled strip and hot rolled strip are also sealing plates? What's their function?
Secondly, strip and steel strip should be about the same, no less than a narrow strip of steel bar, the equipment configuration is the same
Q:Specification and use of cold rolled strip
Cold rolled strip specifications: cold rolled strip and sheet, the general thickness of 0.1 ~ 3mm, width of 100 ~ 2000mm; are hot rolled strip or steel plate as raw material, at room temperature by cold rolling rolling. Grades are generally: SPCC, Q195, Q235-B.
