The previous article mentioned the reason for price differentiation in steel roofing and walling which according to the quality. In this article, we will mention the price of steel roofing system in details.
The factor affecting the metal sheet budget
If mention only material specification, normally the price of steel roofing/walling/ceiling is a little bit different under the same specification (thickness, coating, and strength of steel). The price is varying around 5-15% depends on the profile width normally around 650-750 mm. excepting some specific profile which has the special width of 300 mm. or 950 mm.
But if we talk about the whole roofing system consisting of roof sheet and fixing tools, it will be a lot different around 60-80% because each system has fixings method.
- Bolt System: fixing tool is the screw
- Boltless Roofing System: fixing tool is the clip/connector
• For KS KlipFix39: uses clip and conceal-fixed by place sheet over clips
• For KS KlipSeam60, KS KlipSeam110: use connector and install with 180 degree seaming - Standing Seam Roofing System: fixing tool is the Move Clip/connector and install with 360 degree seaming
Moreover, it is not included other standard accessories or anti-leakage accessories which increasing more budget such as:
- Standard Flashing for connecting such as ridge flashing or gable flashing excepting in some projects needed the special flashing which will increase the budget.
- End closer or Top closer, this Rib ends stop mostly be used to block off the rib cavity for preventing to enter building from birds and mouse.
- Louvres and louvre connector mostly to ventilate and prevent rainwater, bird and mouse.
- If using the thermal insulation or sandwich roofing, it will need to use the Tower support to collapse of the sheet
- If using rooftop or other accessories such as KS VentFlow (roof ventilation system), KS Safety Rooftop (fall protection equipment), or KS Solar Rooftop
Need a specific accessory that is the standard flashing and End closer which increasing about 10%. For other factors, it depends on the budget, building type, and specific requirements such as heat reduction, noise reduction, more air ventilation, more safety, or electricity generating
Conclusion
The price of steel roofing/walling/ceiling only material specification under the same specification (thickness, coating, and strength of steel) is a little bit different around 5-15% depending on the width of the profile. If mention to roofing system consisting of roof sheets and fix tools, it will vary around 60-80% because each system has different fixing method. Moreover, the standard accessory or anti-leakage accessories is an important factor which can increase more the budget
