Color coated galvanized steel coils are available in a variety of colors and patterns to meet different styles and uses. The colorful coating also makes PPGI steel more corrosion resistant and durable. PPGI steel coils have excellent processing properties.

When choosing greenhouse poles, it is generally more appropriate to choose 1.5 mm to 2 mm steel pipes.
If it is a larger greenhouse, such as a greenhouse of thousands of square meters, it is recommended to use 2 mm or even thicker steel pipes, so that it can better withstand the weight of strong winds and snow.
The thickness of the steel pipe is a very important parameter because it is directly related to the service life, load-bearing capacity, and wind resistance of the greenhouse.

1. Check the supplier
Choose a reliable supplier. Investigate the supplier's reputation through multiple channels.
2. Material standards
Specify the stainless steel material in the contract and specify which stainless steel plate is purchased, such as 304, 316, etc. At the same time, the material standards should be specified, such as JIS, ASTM, GB/T, etc.
3. Clarify the contract details
When signing the contract, the specifications and quantity of the materials should be checked to avoid differences between the two parties on the specifications and quantity. At the same time, the delivery date of the stainless steel material should be clarified, communication with the supplier should be maintained according to the specified delivery date, and attention should be paid to the production progress of the stainless steel.
4. Quality inspection
Check whether the surface of the stainless steel is smooth, clean, and undamaged and whether the patterns and marks are clear. The size, material, precision, and surface quality should meet the requirements of the contract; the standards should meet the industry or national standards.
5. Quality Guarantee
If the customer requires, the stainless steel should be accompanied by a quality guarantee. When purchasing stainless steel, you can ask the supplier to provide a quality guarantee with an official seal.
