Glass wool adopts the most advanced centrifugation technique to fiber glass fibrosis, Such products has large amount and very thin glass fiber inside. Its total surface area is very large also, so as to strengthen the resistance of the air, making the air unable to flow and eliminating the air convection heat transfer; Similarly, huge friction decays vibration of the sound propagation carriers - air quickly, which ensures glass wool's good thermal insulation and sound absorption effect. It is also good material for sound absorption and noise reduction in steel structure building. 

2)Rock Wool Sandwich Panel

Rock wool sandwich panel is not better than polystyrene and polyurethane sandwich  panel with regard to sole weight, heat conduction, compressive strength, water absorption rate and other physical and mechanical properties. However,  it can be used under the service temperature of 600℃. Besides, this type panel possesses the outstanding feature of being level A incombustibility, thus rock wool sandwich panel  serviceable range is expanded to light weightconstruction materials for high requirement on fire-protection rating.

4. Transportation

Steel structure is mainly composed of steel column, steel beam, steel frame and the rigid support and so on, so steel structure component volume is larger, The mainly transportation for export is as follow:

1) Seaworthy

In general, after customer order, our engineering technology department design the steel structures will be according to the 40 'HQ and 40' open top container inside size to design the shipment, in most cases, we use 40 'HQ and 40' open top shipping container shipment to pack steel structures.

2) Package for the steel frame

If you want to use the 40 HQ container to transportation the whole steel structure product. You can do the steel frame to package ,use the cable wire to fix. But you must paid for the steel frame and baling charges.
