Equipment for painting metal structures: specific features

Powder painting of metal structures and any other metal items requires a competent selection of equipment. It must be complied with the technological requirements for painting metal structures and perform high-quality specific processing of products before painting.

Powder coating equipment differs in terms of its operation, technical characteristics and price.

In order to select the necessary tools, we recommend you get acquainted with the features of each unit. But the purchase should still be made only after consultation with specialists.

Equipment for painting metal

You can use a pneumatic spray gun, paint sprayer, stand-alone installation for metal coating. Spray guns are needed for direct coating of the product.

The main element of any sprayer type is the gun. Its characteristics and accuracy of work directly affect the quality and uniformity of the coating. Therefore, before buying this tool be sure to check the integrity and tightness of the device.

The spray gun might be pneumatic or electric. The first one is professional – used in large companies and at car services. They are more durable and hardwearing. A large number of products can be coated with these spray guns. Thanks to them, paint for metal structures will not clump, stains and defects will not form on the coating.

Pneumatic units are powered by compressed air. For this they have a special compressor. It supplies air to the system. In this version of the spray gun, it is very important to check the quality of the compressor. Its technical characteristics affect whether you can work with complex products, and whether the gun will work accurately.

Electric spray guns work thanks to electricity. They are more mobile and practical. Such units are the best option for small industries. Electric spray guns are lightweight and ergonomic. It is convenient to use them to cover metal furniture, pipes, etc.

Autonomous units are best used for large volumes of work, if it needs to be done very quickly and with the highest quality. They provide the ability to connect multiple guns.

Powder coating technology

Powder paint is an excellent anti-corrosion paint for metal, which also has excellent decorative properties, durability and wear resistance. But improper application can lead to the fact that the powder will not have the required properties.

In order to cover metal structures with high quality, it is not enough just to buy a high-quality spray gun. You, also, need a spraying chamber and a polymerization oven.

Before starting painting, it is necessary to prepare the surface: clean it from all dirt by sandblasting or shot blasting and dry it. The metal may need to be phosphated, chromated or passivated.

After that, the metal structure must be grounded. And paint can be applied.

Then it goes to the polymerization oven, where the coating is formed.

For high quality and uniformity it is obligated to follow the powder application technology. Preparation plays a decisive role. Do not skip this step, otherwise you will not be able to get the necessary result.
