国内彩涂钢板用户对钢板品牌关注较少。由于国内大部分彩涂钢厂只有一种钢材，即DC51（因为采购的热轧钢板或硬盘管基本上是钢），一些彩涂钢厂尝试在热镀锌生产线上生产全硬钢（S 550）或高强度钢（S 350等）。基体的质量和化学成分难以控制，质量稳定性差。稳定性差会导致模板性能大幅度波动，导致模板性能恶化。
792、日本的JISG 3302、欧洲的JISG 3321、EN 10215和EN 10147等。
高强度结构钢（hss）：根据欧洲标准，hss可分为四种不同强度的钢。普通cq级钢的屈服强度分别为280mpa和345mpa。宝钢生产的ts 280 gd和ts350gd是两种钢。与普通cq相比，hss钢具有以下优点：1。由于屈服强度低，具有良好的耐火和抗震性能；对于较厚的钢板，可生产大跨度拱板；一般外墙和屋面板可比cq材料薄，节省材料消耗。全硬钢：通过控制退火温度来提高钢板屈服强度的钢。按国际标准，屈服强度≥550mpa，抗拉强度≥570mpa。这种材料强度高，延伸率低。它适用于浅钢板的使用，大大节省了材料的使用。它也是各国开发的一种钢材。国外标准也引进了高强度、高塑性的材料。低合金高强度钢（hsla）是一种在炼钢过程中加入强化合金元素的钢，但由于其强度高，在钢铁工业中得到了广泛的应用。由于低合金钢的还原率只能在轧制过程中提高，因此hsla钢很少用作薄壳结构的彩涂板（另一个缺点是成本高）。
Domestic color coated steel plate users pay less attention to steel plate brand. Because most of the domestic color coated steel plants only have one steel, namely dc51 (because the purchased hot-rolled steel plate or hard disk tube is basically steel),
some color coated steel plants try to produce all hard steel (s 550) or high-strength steel (s 350, etc.) on the hot-dip galvanizing production line. The quality and chemical composition of the matrix are difficult to control, and the quality stability
is poor. Poor stability will lead to large fluctuations in performance, resulting in deterioration of template performance.
For buildings, bearing capacity (wind load, snow load, construction personnel and machinery), building span, purlin spacing design, etc. all depend on the strength of steel plate. For the maintenance structure of color coated aluminum galvanized sheet,
there are corresponding standards abroad. For example, TM 653 in the United States, ASTM 792 in the United States, JISG 3302 in Japan, JISG 3321, en 10215 and en 10147 in Europe, etc.
Steel can be divided into CQ (general commercial grade), DQ (general
stamping), HSS (high strength structural steel) and FH all hard steel).
CQ (general commercial grade): common products produced by Baosteel, such as TST 01z, tdc51 or tsgcc. The yield strength before coating is between 260-320 MPa. After the color
coating, if the matrix is aluminum killed steel, its ultimate strength will be improved, accompanied by the deterioration of elongation. The tensile strength of steel is 350-400mpa, and the yield ratio is slightly higher than that of structural steel.
DQ (general stamping): as the general construction color steel plate is roll bending or composite sandwich, the stamping performance of the material is not high, so it is rarely used in the construction field (except for some door and window color
High strength structural steel (HSS): according to European standards, HSS can be divided into four kinds of steel with different strength. However, the yield strength of common CQ grade steel is 280 MPa and 345 MPa respectively. TS
280 GD and TS 350 GD produced by Baosteel are two kinds of steels. Compared with common CQ, HSS steel has the following advantages: 1. Due to the low yield strength, it has good fire resistance and seismic performance; for thicker steel plate, it can
produce large-span arch plate; generally, the outer wall and roof plate can be thinner than CQ material, saving material consumption. All hard steel: steel that improves the yield strength of steel plates by controlling the annealing temperature. According
to international standards, yield strength ≥ 550MPa, tensile strength ≥ 570Mpa. This material has high strength and low elongation. It is suitable for the use of shallow steel plate, greatly saving the use of materials. It is also a kind of steel developed
by various countries. Foreign standards have also introduced materials with high strength and plasticity. Low alloy high strength steel (HSLA) is a kind of steel with strengthening alloy elements in the process of steel-making, but because of its high
strength, it has been widely used in the steel industry. As the reduction rate of low alloy steel can only be increased during rolling, HSLA steel is rarely used as the color coating plate of thin shell structure (another disadvantage is high cost).
In order to ensure the shape of the final product of the color coated steel plate, the strength grade of the steel plate and the shape of the profiled steel plate are closely related to the processing machinery.
