Choosing a suitable polycarbonate corrugated roof panel requires
consideration of multiple aspects:
Application scenarios
If used for residential balconies, carports, etc., with high
requirements for lighting and aesthetics, transparent or light
colored boards with high transparency and beautiful colors can be
selected, with a thickness of about 1.0-1.5mm to meet the needs.
The roof lighting of industrial plants needs to consider the large
span and bearing capacity, and may require the selection of panels
with a thickness of 2.0mm or more to ensure safety and durability.
Agricultural greenhouses require boards with good transparency and
insulation properties. Transparent or light blue boards with a
thickness of about 1.2-1.5mm can be selected.
Board performance
Impact resistance: If the area frequently experiences severe
weather conditions such as strong winds and hail, it is necessary
to choose panels with strong impact resistance to ensure that the
roof panels are not easily damaged in extreme weather conditions.
Weather resistance: Roof panels exposed to outdoor environments for
a long time should have good weather resistance and be able to
resist the erosion of natural factors such as ultraviolet rays,
rainwater, and high temperatures, ensuring that they do not fade or
deform during long-term use. You can view the weather resistance
level and relevant testing reports of the product for evaluation.
Transparency: Select panels with appropriate transparency according
to the requirements for indoor lighting. For example, places that
require sufficient natural light, such as greenhouses, sunrooms,
etc., should choose transparent panels with a light transmittance
of over 80%; For places that do not require high lighting or
require a certain level of privacy, frosted or colored boards with
slightly lower light transmittance can be chosen.
Fire resistance: In some places with high fire resistance
requirements, such as factories, warehouses, etc., polycarbonate
corrugated roof panels with good fire resistance should be
selected, such as products that meet flame retardant B1 level.
Specification and size
Thickness: Common thicknesses include 0.8mm, 1.0mm, 1.2mm, 1.5mm,
2.0mm, etc. Generally speaking, thinner sheets can be chosen for
areas with small spans and low load-bearing requirements; If the
span is large or there are special load-bearing requirements,
thicker plates need to be selected.
Length and width: The appropriate length and width should be
selected based on the actual size of the installed roof, minimizing
splicing to improve waterproofing performance and aesthetics. If
there are special shape or size requirements for the roof,
customized panels can also be considered.
