Frequently Asked Questions

Can these black corrugated plastic sheets be used outdoors?

Yes, the polypropylene material is moisture resistant and suitable for temporary outdoor use, such as site signage or short-term protection. For long-term external applications, exposure to strong sunlight and weathering may eventually affect appearance, so periodic inspection and replacement is recommended.

How can I cut and shape the 4mm corrugated plastic sheets?

The sheets can be cut easily using a sharp utility knife and a straight edge. Several light passes are usually better than one heavy cut. They can also be scored to create folds or simple creases, allowing you to form boxes, edge protectors or angled panels.

What is the best way to fix or mount these sheets in place?

Fixing method depends on the surface and application. Common options include strong tapes, adhesive pads, construction adhesives, staples (into timber), screws with large washers, or cable ties through pre-drilled holes. Always ensure the chosen method is suitable for the load, environment and substrate.
