Specification
KR18 and KR24 are both types of standing seam metal roofing profiles, often used in commercial, industrial, and even residential buildings. They are named based on the width of the panels: KR18 is 18 inches wide, and KR24 is 24 inches wide. Let's break down their applications and differences:
----------------------------------------------------------------------------------------------------------------------------------
Applications of KR18 and KR24 Panels
✅ KR18 Standing Seam Roof Panel Applications:
* Commercial buildings: Warehouses, factories, shopping malls, etc.
* Residential buildings: High-end homes, villas, or houses requiring sleek, modern roofs.
* Institutional buildings: Schools, hospitals, government buildings.
* Slope roofs with long runs: Due to its narrow width and better wind uplift resistance.
* Architectural projects: Where tighter seam spacing is preferred for aesthetics and performance.
* Portable roll forming usage: KR18 panels are popular with portable roll forming machines, especially for on-site roofing.
✅ KR24 Standing Seam Roof Panel Applications:
* Industrial buildings: Larger industrial facilities with expansive roofs.
* Agricultural structures: Barns, silos, sheds, etc.
* Budget-conscious projects: Where material savings are important.
* Commercial buildings: Used in areas where wider panels and faster coverage are more efficient.
* Low to medium slope roofs: With fewer seams and easier water drainage.
----------------------------------------------------------------------------------------------------------------------------------
Additional Considerations
* On-Site Forming: KR18 is more common with portable roll forming machines due to easier transportation and flexibility on job sites.
* Structural Support: KR18 panels often perform better on open purlin systems due to more frequent support points, while KR24 can span larger gaps with proper panel thickness.
* Water Shedding: Both are suitable for low-slope roofs, but KR18 may handle water better due to closer seams.
----------------------------------------------------------------------------------------------------------------------------------
Summary
* Use KR18 when you want better wind resistance, tighter aesthetics, or plan to do on-site fabrication.
* Use KR24 when you need to cover a larger area quickly, are working on a budget, or where structural load is less demanding.
