Our factory was established in 1996, meanwhile begin installation, anticorrosion and heat-preservation steel works. Our registered capital is RMB10,180,000, after several years development, we mastered a complete set of technologies for profiling equipment (SM40, SM50).now, our company occupied five sets of double profiling equipment(SM40,SM50), with annual production capacity of steel silo exceed 800,000m3.
Our main products including Agricultural silos, Industry silos, Storage silos and Environmental production silos and so on. We can provide high quality and inexpensive goods in accordance with customer requirements. Our products have sold to home and abroad, such as Austrilia, Russia, Mexico, Cote d’lvoire and other countries. Looking forward to more customer, work hard for your and our development together.
We have strong technical force including more than 20 professional design persons, our hardware equipment is perfect, we have 20,000 square meters of manufacturing plant contained more than 20 sets of production equipment, such as SM40, SM50 spiral bit edge line of manufacturing complete sets.
Our annual steel silo project contracting is 800,000 cubic meters. The projects spread to all of Chinese provinces, autonomous regions and municipalities. We have hundreds of engineering models, welcome new and old clients to visit and guide.
1)We have a high-efficient work team. The construction period will never exceed our estimated days. For example, when we estimate 15days for installation, we’ll finish in a period that shorter than 15days.
2)We have a good-skilled installation team. Most of them can operate the special equipment
Very well. The others are good at welding. They have more than 6 years’ work experience.
1,The silo is built directly on spot by using special machineries due to their advanced technology, this enable us to build cylinders from 1 meters to 25,00 meters diameter and the height can be up to 35,00 meters. The engineers, the designer and the user himself should exploit the utmost the space available to construct.
2,The silo has an flat smooth wall inside, a very important device which avoids stagnation of dust .
3,The silo can be built with an absolute air- watertight system: this advantage allows to storage both liquid products and solid products as well as being extremely useful for the storing of cereal products themselves.
4,The silo is different from corrugated one and is suitable to any kind of bulk storage; that it means aggregates (like cements, coal, gypsum, carbonates, etc), sludge, biomasses, chemical, plastic products and liquids can be stored in it.
