We offer efficient longitudinal structures for bulk storage according to different projects conditions.The most common way to store bulk materials is stacking them in long, prismatic piles. So its widely used in storing large-volume bulk materials all over the world. Spatial structure is mainly normal structure of them as its safe and easy to assembly. It also has good properties in heat and sound insulation, waterproof and fire prevention. Its fast and easy to install which greatly shortens the construction time and reduces the costs. The whole structure is easy to maintain and the service life is more than 50 years. The longitudinal structures are particularly suited for highly corrosive environments. The structure tubes is plated by steel or aluminum, and either of these materials can be processed with a highly heat resistant epoxy or polyester coating. The cladding can be steel, aluminum, fiber-reinforced plastic, polycarbonate, or combination of them. For some aggressive interior environments, FRP cladding can be applied to the internal structure. We are very professional and experienced, as we have built a long-term relationship with many countries, such as the Philippines , Saudi Arabia, India, Togo, Nigeria and Malaysia, etc. We have completed more than 1500 projects with full capability of research, design, fabrication, construction and supervision service both home and abroad.
