Mobile steel framed hangars covered by PVC is one of the leading alternative to traditional steel covered halls. Design, calculations and manufacture are according DIN 18800 and ISO 9001 quality standards.  Width of the hall can be up to 80 m without the use of supporting columns. Additionally can be designed and installed ventilation, heating and lightning.   Frames Wind and snow loads are calculated according to EC3, standard prefabricated halls are calculated for 1.8 kN/m2 of snow and 32 m/s of wind loads, safety factor 1.5. Frame construction is produced from structural steel, the surface of which is sounded (ISO 8501-1:1988 Sa-2,5) and covered with epoxy paint (120 µ) of RAL 7000 color. Step between frames for standard production is 3 m. All frame elements are designed to be as much as possible easily erectable and dismountable. Maximal construction element length not exceeds 13 m.   Cover Cover is manufactured of light translucent PVC fabric, flame retardant (DIN4102B1/M2 standard), both sides of which are covered by acrylic layer. PVC fabric delivered in rolls, which is welded into one piece of covering by high frequency welding technology what makes hangar cover absolutely hermetical. PVC fabric elasticity gives an opportunity to avoid foundation as well as possibility to erect a hall on uneven site, does not react storing bulk chemicals. There is no need to use artificial lightning in a day time as roof fabric produced from light translucent (10-17%) fabric.     Fabric durability andantages   Basic hangar package: - frames; - PVC cover; - Sliding gates (quantity and dimensions depending on chosen hall model.     Isolation Installing additional PVC inner layer which provides enhanced insulation characteristics (~3.0 W/ m2 K) and helps to avoid condensate problem. .   The higher < 1 W/m2 K coefficient can be reached installing isolation material in-between of two PVC fabric layers.   Hall walls can be covered by profiled steel sheets.   Colors Roof is commonly produced from white light translucent fabric. Walls can be chosen by the customer.       Sliding gates (quantity and dimensions depending on chosen standard hall model)     Ground fixing Base plates are fixed by metal anchors to the ground or screwed by nuts to the foundation.     Lifting equipment     Guarantee Guarantee period is 3 years.
