Product Description:

Product  Brief  Introduction

 

COLORED CORRUGATED STEEL SHEET FOR ROOFING 


 --- Corrosion resistance: Pre-coated steel offers excellent corrosion resistance achived through continuous hot DIP galvanization and corrosion resistant primer/polyester coating. Protection is achieved when zinc and steel are together in the presence of moisture; The zinc protects the steel by galvanic action

Q:What can be painted on galvanized steel sheet?
Zinc coating in the atmospheric environment after exposure, the surface will form a zinc salt (also known as white rust), before coating the paint, these zinc salts must be completely eliminated. The most effective treatment is the light sweep sand blasting method; if it is impossible to use sandblasting, you can use wire brushes or steel wool and full fresh water to remove zinc salts by mechanical cleaning and washing.
Q:What is the difference between hot rolled steel and controlled rolled steel plate? Can two plates be used interchangeably?
The rolled steel plate is used to achieve the ideal special performance by controlling the amount of deformation, deformation and temperature. Having higher added value and higher price. Interchangeable, but not a good choice!
Q:How do you calculate the square footage of a ton of steel?
The width of the sheet is 500~1500 mm; the thickness is 600~3000 mm. According to the type of steel sheet, ordinary steel, stainless steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet; according to professional use, with drums board, enamel board, bulletproof plate; surface coating and plating, plating with zinc thin plate, tin plate, plating lead sheet, plastic composite plate
Q:What is the difference between the zinc plated color guide and the profiled steel sheet?
Profiled steel sheet Yaxing, GangBan, English Name: profiled steel sheetRoof and wall panels are usually 0.4 to 1.6 millimeters thick and used for load-bearing slabs or silos with a thickness of 2~3 millimeters or more. The wave height generally ranges from 10~200 mm. When not reinforced, the ratio of height to thickness should be controlled within 200. When the long roof panel, the slope can be used from 2 to 5%, while the deflection is less than l/300 (L for the calculation of span length). At present, part of the waveform used in the construction is shown in Figure II, commonly used for profiled steel sheets.Because the original plate is very thin, the quality of the anticorrosive coating directly affects the service life of the profiled steel sheet. In order to meet the requirements of processing and rust prevention, the coated steel plate shall be examined in accordance with the relevant provisions. Under normal circumstances, thin steel plate can also be used according to the requirements, after pressing type, and then coated with anti rust paint, or use stainless steel sheet, the original plate.
Q:What kind of steel plate is Q234?
This brand is one of the most commonly used low carbon structural steel grades. The utility model has the advantages of good plasticity, definite strength and good weldability. Used in the manufacture of parts that are less stressed, such as screws, nuts, gaskets, etc., welding parts, stamping parts, construction and other steel parts.
Q:How to introduce carbon steel plate?
Grade: the cases of Q235-A F, said the sigma s Note: Q is more than 235MPa grade yield strength of A grade (ABCD four), F boiling steel characteristics: low price, process performance (such as welding and excellent cold formability). Applications: general engineering structures and general mechanical parts. Such as Q235 can make bolts, nuts, pins, hooks and less important mechanical parts, as well as the construction of the thread steel, steel, steel and so on
Q:Which is good, z15 grade steel plate and z25 grade steel plate?
It is obvious that the fracture resistance of lamellar fracture is stronger than that of fracture shrinkage, that is, the lamellar tearing resistance of Z25 is better than that of Z15.
Q:Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
The information of the building is incomplete and can not be determined. The welding technical parameters will affect the welding method, welding current, welding voltage, welding environment and specifications
Q:How much is one meter for laser cutting steel plates?
The algorithms on the market price are generally:Cut the price of one meter = the thickness of the material to be cut * 1.5 (excluding the price of material costs)(for example: compare 6 millimeters of low carbon steel plate laser cutting one meter price: 6 (plate thickness) * 1.5=9 yuan / meter10 mm low carbon steel, laser cutting one meter price: 10 (plate thickness) * 1.5=15 yuan / meter12 mm low carbon steel, laser cutting one meter price: 12 (plate thickness) * 1.5=18 yuan / meterAccording to this formula, we can get the price of cutting one meter with different thickness
Q:Should the carbon fiber reinforce the steel bar on the side of the beam?
Not necessarily, mainly depends on how the design is calculated, usually put 100~200mm carbon fiber layering
