How to distinguish the quality of wrought iron guardrail

The first is to measure the material thickness of the wrought iron guardrail, whether it is consistent with the prior contract or agreed material thickness. This is a very basic quality standard. Materials must be used in strict accordance with the requirements, especially engineering iron fences, which usually have design drawings and technical requirements. If it is not carried out according to the requirements, it will affect the later project acceptance. Manufacturers or project buyers will add unnecessary trouble.

The rust prevention of wrought iron fence is very important. If the environment is harsh and anti-rust treatment is not done well, the service life of the iron fence will be greatly reduced. It mainly depends on whether it has been galvanized. Hot-dip galvanizing has better anti-rust treatment for wrought iron fences.

Surface paint is also the focus of quality appraisal. The common ones are baking varnish, fluorocarbon paint and ordinary paint. Customers need to specify which paint method to use on the surface of the wrought iron fence according to different usage environments. Baking paint is also commonly known as electrostatic spraying. After the spray booth is heated, the plastic powder on the surface will form a layer of paint film, which has strong adhesion, is smooth and smooth, and has a good effect. Available in matte and glossy shades. Otherwise, prices are moderate.
