Corten steel decorative perforated metal panel cladding Sheet

Corten steel, also called Weather Resistant steel or Atmospheric Corrosion Resistant steel, it is known as a low cost and highly effective material.

Corten steel is classed as being a "self -protecting "steel for its "patina "which results from protective surface oxidation and develops during exposure to the atmosphere; The oxide layer that gives the steel its distinctive appearance and enhances weather resistant capabilities compared to standard steels, also the improved corrosion performance can lead to improved service life.

Corten steel plate
1. Weather resistant structural steel. The anticorrosive properties of weather resistant steel are better than those of other
structural steels in many applications. The steel is self-protecting: The rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion. The steel is an economical, long-lasting and fully recyclable material.

2. Corrosion resistant steel - Weathering Steel
Weathering steel is a copper chromium alloy which is 'self-healing'. The untreated steel reacts to chemicals in the atmosphere as part of the oxidation process and generates its own protective layer of rust. This layer (or patina) prevents the steel from further deterioration and replenishes itself over time.

3. Atmospheric corrosion resistant HSLA structural quality steel is stronger & tougher than carbon steel, is ductile, highly
formable & weldable. HSLA structural steel features atmospheric corrosion resistance, which is crucial in structural applications.Atmospheric corrosion resistant steel is intended primarily for use in structural members, where savings in weight (mass) and added durability matter.

Plate is used in truck frames, brackets, crane booms, rail cars and other comparable applications.

Mill finish

Step 1. The steel surface by shot peening or pickling to remove the surface scale.

Step 2. Preparation of weathering steel surface treatment agent, the weight percentage of 0.1% ~ 3% NaCl, 0.3% ~ 3% FeSO4 , 0.1% ~ 3% CuSO4 and 0.3% ~ 3% NaHSO3 mixed with water and poured into the barrel, Uniform until the solution was sky blue.

Step 3. Will be equipped with a good surface treatment agent into the sprayer, spray evenly on the steel surface for 3-5 seconds to the surface of the steel into a brown, spray finished once, so that the steel surface dry naturally, this time with suction absorbent material steel structure The lower part of the residual liquid, to ensure that the upper and lower drying time consistent until the steel structure after drying, repeat the spraying and drying process 2 times to ensure that the corten steel surface to generate a uniform and dense rust layer.

Due to the high corrosion resistance of corten steel sheets, it normally takes from 1 to 2 years from a completely new steel sheet to the formation of a stable, dense, rust-red protective layer (50-100mic thick) in natural environments. For some dry areas May be even longer.If you want to generate a simple uniform rusty yellow, it also takes about 1 month.In the process, the components of the color will occur uncontrollably, from blue and black to orange red, then rusty red, the last reddish brown Dramatic, uneven change process.
