Urumqi profiled steel plate

Xinjiang profiled steel sheet yaxing gangban English name: profiled steel sheet

Commonly used plate thicknesses for roofs and walls are 0.4 to 1.6 mm; used for load-bearing floor slabs orsiloThe thickness reaches 2 to 3 mm or more.wave heightGenerally ranging from 10 to 200 mm. When not reinforced, the height-to-thickness ratio should be controlled within 200. When using the full lengthroof panel, the slope can be 2 to 5%, thenDeflectionNo more than l/300 (l is the calculated span length). Some waveforms used in construction are shown in the figure [profiled steel plates are commonly usedWaveform graph]。

Because the original plate of Urumqi profiled steel plate is very thin,Anticorrosive coatingThe quality directly affects the service life. In order to adapt to the processing and anti-rust requirements,coated steel plateVarious inspections must be carried out in accordance with relevant regulations. NormallyThin steel plateAccording to the requirements of use, anti-rust paint can be applied after pressing, orStainless steelOriginal thin plate.

Xinjiang profiled steel plates are used as housing panels for industrial plants,wall panelWhen there is generally no thermal insulation requirement, the amount of steel used per square meter is about 5 to 11 kilograms. Available when there are thermal insulation requirementsMineral wool board、glass wool、StyrofoamWaiting for workinsulation material. Made of Xinjiang profiled steel plate and concreteCombined floor slab, can be omittedwooden formworkand can be used asload-bearing structure. At the same time to strengthenUrumqiProfiled steel plate and concretebinding force, it is advisable to pre-weld studs on the steel plate or press two-wayStiffener。

Product classification

According to the substrate coating, there are the following 6 categories:

1) galvanized steel plate

Galvanized steel pressASTMThe weight of the double-sided coating in the three-point test is 75~700g/㎡. The more commonly used galvanized steel plates in construction applications are Z275 and Z450, and their double-sided galvanizing amounts are 275g/㎡ (single-sided coating of the steel plate).Smaller thicknessis 19μm) and 450g/㎡.

2) Aluminized steel plate

There are two common types of aluminized steel plates for construction:

(1) Used in environments with high heat resistance requirements: The metal coating of this type of aluminized steel plate contains 5 to 11% silicon, the alloy coating is thin, the weight of the aluminum coating is only 120g/㎡, and the minimum thickness of the single-sided coating is 20 μm.

(2) Used in highly corrosive environments: Almost all of its metal coatings are aluminum, the metal coating is thick, the weight of the coating is about 200g/㎡, and the minimum thickness of the single-sided coating is 31μm.

3) Galvalume steel plate

Galvanized steel plate, also known as sub-lead gold steel plate.

(1) It is a double-sidedhot dipGalvalume-coated steel sheet products, the steel sheet base material complies with ASTM A792 GRADE 80 or AS1397 G550, itstensile strengthis 5600kg/cm. The metal coating is composed of 55% aluminum, 43.5% (or 43.6%) zinc and 1.5% (or 1.4%) silicon. It has the long-termCorrosion resistanceandheat resistance; Zinc protects cutting edges and scratch gaps; while a small amount of silicon can effectively prevent aluminumzinc alloychemical reactionGenerates chips and makes the alloy plating more uniform.

(2) The three-point test weight of double-sided coating is 150, 165, and 189g/cm. Commonly used in constructionGalvalume steel plateIt is AZ150, that is, the coating weight per square meter is 150 g, and the minimum thickness of the single-sided coating of the steel plate is 20 μm.

4) Galvanized aluminum steel plate

It is a product containing 5% zinc and aluminum andMixed rare earthAlloy double-sided hot-dip coated steel plate, the double-sided coating weight is 100~450g/㎡ in three-point test.

5) GalvanizedAlloyingsteel plate

is a kind of heatgalvanized steel plateHeat treatment to make the surface purezincFor double-sided galvanized steel products where all coatings are converted into Zn-Fe alloy layers, according to existing process conditions, the weight of the converted coating is calculated as zinc, with a maximum of 180g/㎡.

6) Electro-galvanized steel plate

is a pureElectro galvanizedCoated steel plate products, the maximum weight of double-sided coating is 180g/㎡, and are generally not used outdoors.

on building roofs (andcurtain wall) are more commonly used in colored galvanized steel sheets and coloredGalvalume steel plate。
