Q690E carbon steel plate sheet bare surface

Galvanized sheet refers to the steel plate with a layer of zinc on its surface. Galvanizing is an economic and effective anticorrosion method of steel plate. Galvanized sheet can be divided into hot galvanized sheet and electro galvanized sheet according to production process. The zinc layer of hot-dip galvanized sheet is thick, which is used for Q690E carbon steel plate sheet parts with strong corrosion resistance. The thickness of zinc layer of galvanized sheet is thin and even, which is mostly used for painting or indoor products.

Since it was established in 2000. Based on the domestic rich Q690E carbon steel plate sheet product resources and the great steel demand of the international market, our Q690E carbon steel plate sheet service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

A plasma cutter uses a stream of compressed gas (air, nitrogen, argon, etc.) and a consumable wire electrode as the two primary feedstocks of the steel cutting process. The electrode sends a high electrical charge through the gas, raising its temperature to the point of ionization to generate extremely hot plasma (~20,000°C). This plasma is directed through the cutting tip to create a highly focussed beam, with velocities approaching the speed of sound.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and Q690E carbon steel plate sheet pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
