PrimeHome’s steel structures utilize a two-layer rust-proofing process: galvanizing + spray-painting (110μ/㎡). Many suppliers only use spray-paint for corrosion protection, with a density of only 80μ/㎡, which leads the structures to rust within 2-3 years, and significantly shortens the service life. However, PrimeHome first galvanizes and then spray-paints them at 110μ/㎡, which typically achieves rust protection for over 10 years, and significantly extends the service life of container houses.
