Product Inquiry

Container steel:

Type	Grade	Specification mm	Standard	Application
Container	SPA-H	1.2~6.0 ×900~2000	JIS G3125-2004	Container
	LGC450	1.2 ~6.0 ×(900~ 1300)	Technical agreement	High-strength container
	LGC550	1.2 ~6.0 ×(900~ 1300)	Technical agreement	High-strength container

SPA-H is the first generation of steel products for container, with mature technology and stable quality, it has been widely used in marine logistics containers . LGC450 and LGC550 are the second generation of steel for high-strength containers, and the weather resistance index is the same as that of the first generation of containers. Using micro-Ti treatment, the yield strength has been increased by 100~200MPa, which is widely used in highway and railway container transportation business with the characteristics of high strength, easy processing and forming, energy saving and weight reduction.

The coating-free super weather resistant steel products with strength of 420~800MPa have been developed , which have the characteristics of high strength, excellent corrosion resistance, easy processing and environment protective. It can adapt to working conditions such as inland atmosphere, industrial pollution atmosphere, ocean atmosphere.

LGNHP800 is about 25% lighter than traditional materials when applied in manufacture photovoltaic supports. It can also be used exposed without coating under C3 environment, and the thickness reduction is less than 0. 1mm/a in 30 years.
