Strong ultraviolet rays and rainy weather have turned outdoor stainless steel billboards into "consumables" - many community billboards have problems such as paint fading, rusty frames, and glass cracking in less than a year of use. This not only affects the appearance, but also requires frequent replacement, increasing costs. These problems are actually caused by the Kunming stainless steel billboard manufacturer's failure to do a good job in outdoor protection.

Reliable Kunming stainless steel bulletin board manufacturer will do "triple protection" to ensure durability: the material is 316 stainless steel, which contains molybdenum and is more than 2 times stronger than 304 in UV and rain corrosion resistance. The thickness of the frame steel pipe reaches 2.0mm, and the wind load resistance reaches level 12;

The surface adopts fluorocarbon spraying process, with a coating thickness of more than 60μm. After 2000 hours of ultraviolet aging test, the fading rate is less than 5%; the glass is made of 5mm thick tempered glass, which has an impact resistance 3 times that of ordinary glass to avoid breakage caused by wind and rain.

In terms of technology, the welding area of the bulletin board is treated with anti-rust treatment, and is coated with 2 layers of anti-rust paint + 1 layer of topcoat; a 15cm wide rain shield is installed on the top to prevent rainwater from penetrating into the interior and damaging the poster. Take the stainless steel publicity board purchased by a park in Kunming as an example. This publicity board has been in use for 4 years and still maintains a good appearance. The paint surface has not faded significantly and the frame has no traces of rust.

When purchasing, you should choose a Kunming stainless steel billboard manufacturer with experience in producing outdoor billboards and check its past outdoor project cases to ensure that the product can adapt to Kunming's climate and be durable for a long time.
