Roofpro Joist and Floorpro Joist

Open Steel Joist:
Open Steel Joist: Shanghai Open Steel Joist Corporation has been making design research of and manufacturing the steel joist. As long as adopting the advanced technology from North America, in combination with domestic current codes and raw materials, we are committing ourselves to the research and development of steel joist as roof purlin and mezzanine joist which can be produced in industrial mass production. Open steel joist adopts high strength cold formed plate instead of traditional top and bottom chord of hot rolled section. The web of Open steel joist is thin wall welded pipe or rod steel which makes a good joist appearance as well taking a rational advantage of materials feature. The Open joist can reduce the total construction cost for the customer as well maximizing the time saving.

The Open joist can reduce the steel consumption effectively by its structure. If the span is fixed with the same steel consumption, larger load capacity can be acquired by using Open joist. If the load is fixed, bigger span can be also acquired.

Open Corporation has been seeking the more rational utilization of steel in construction. Open products, roof purlin and mezzanine joist, are ideal for saving material and enlarge span.
