How many years is the warranty for galvanized cable trays
Galvanized steel bridge : The general warranty period is 5-10 years, depending on the thickness and quality of the galvanized layer. Lifespan (1-2 years to 10 years): Regular galvanized steel trays have a thinner protective coating and are often exposed to corrosion in humid or corrosive. The warranty period of cable trays usually varies according to the manufacturer's regulations and the usage environment. The following are some factors that affect the warranty period: 1. Materials and manufacturing. Pre-galvanized steel trays offer economical solutions for indoor installations but typically last only 5-7 years in humid environments. Electronic component rooms often have temperature changes. Moisture can form on metal surfaces. This article will introduce the features, advantages, application scenarios, and installation methods of this product, and help you understand why choose this product.
