DETAILS

Flat steel, refers to the width 12-300mm, thickness 3-60mm, rectangular section and a little blunt edge of the steel. Flat steel can be finished steel, but also can be used as a tube blank and a thin slab for sheet metal rolling. Main purposes: flat steel as a material can be used for making hoop iron, tools and mechanical parts, building structures used as structural parts, escalators.
Compared with the traditional steel plate
Special product specifications. Thickness of 8 ~ 50mm, width 150-625mm, length 5-15m, and product specifications Dense pitch, to meet the needs of users, instead of the use of plate, without cutting, you can directly welding.
Product surface smooth. Secondary use of high-pressure water descaling process, to ensure smooth steel surface
Vertical sides, water chestnut clear. Finishing rolling in the second Road, to ensure the two sides of the verticality is good, angle clear, the surface of the edge of good quality.
The scale of the product is accurate, three o'clock difference, the same level difference is superior to the steel standard; The product is straight, the plate type is good. Finishing continuous rolling process, automatic automatic sets of loopers to ensure that no non-steel pile of steel, high dimensional accuracy, tolerance range, three points difference, with the same bad, sickle bend and other parameters are better than the plate, and the plate straight Good degree. Cold cut, length and length precision.
Product material using national standards, and the same plate. Quality and technical standards by YB / T4212-2010 standard production (Q345B / Q235B refer to GB / T1591-94, GB / T700-06 standards)
In the use of more advantages than steel
Flat steel with negative bias rolling, but according to the actual weight of delivery, utilization of steel increased by 1 to 5 percentage points.
Flat steel according to user needs, will be thick, fixed width, fixed-length production, cut for the user to reduce and save processes, reducing labor, material consumption, but also reduce the processing of raw materials loss, time-saving, labor-saving, provincial material. Products have been used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, cranes and other industrial timber.
