PE coated steel EN steel grade S355J0 material roofing sheet

BBNsteel is one of the world-leading suppliers of construction steels for a global industry. We understand the unique demands of EN steel grade S355J0 material building large scale structures in an increasingly budget-conscious economy. Construction steel plates and steel sections are used from the ground up; particularly in civil engineering and large-scale industrial projects. Pilings and baffles are used to lay the groundwork and establish a strong foundational anchor for tall structures like skyscrapers.

The basic phases of EN steel grade S355J0 material, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter EN steel grade S355J0 material steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.

Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
