SPA-H Steel Plates

The SPA-H steel plates are available in a wider variety of shapes, thickness, and dimensions. We have a skilled professional engineer who has a maximum year of the exporter to design this plate in accordance with the international market standards. They cater the specific requirement of the customers before starts manufacturing. This company produces this grade of steel plate in stock as selling worldwide. They provide mill test certification, stampings, and fully traceable products in the affordable range.

Product description

The SPA-H steel plates comes outstanding features and that make it most demanding steel plates in various commercial applications. The SPA-H has good mechanical properties such as high tensile strength, yield strength, stable elongation, and more. The SPA-H is considered as far more than standard requirement. This grade is also considered as weathering steel that is widely used in container industry.

This SPA-H steel plate is delivering with various conditions like hot rolled, cold rolled, normalized, quenched, tempering, etc. this plate is design and supply with surface coating of dark brown oxidation that have deeper penetration , so that it can save your cost of extra outer layer painting and it will prevents this plate from rust. It can also maintain over many years. This grade of steel plate is easily weldable and formable in any structural shapes.

Testing Detail- the manufacturing Company conducts various tests on material to meet the end-product quality. This test includes ultrasonic test, hardness test, intergranular corrosion test, PMI test, third-party inspection test etc.

Packing detail- Packaging is provided by the supplier as per the customer requirement or using standard method. This steel plate is carefully cover using shrink wrap paper and then put in wooden case or boxes so as to avoid damage or rust during the last stage of production.

The manufacturing has expert worker team, they ensure to deliver product in less delivery time. They also ensure you to provide best quality material in lesser shipment. You can buy these SPA-H steel plates from them in market leading prices. They provide various test certification reports and MTC if it is requested by the customers.
