Frequently Asked Questions (FAQ)

Q1: Is 4mm acrylic strong enough for structural or load-bearing use?
A: 4mm cast acrylic is rigid and impact-resistant but not recommended for structural support. For load-bearing panels, consider 6mm or thicker.

Q2: Can you cut the sheets to specific dimensions before shipping?
A: Yes, we provide cut-to-size service with ±1mm tolerance using panel saw or laser machine.

Q3: What is the difference between cast and extruded acrylic?
A: Cast acrylic has better optical clarity, surface finish, and thermal stability. It is preferred for laser cutting and display-grade applications.

Q4: How should I cut the acrylic sheets if I want to do it myself?
A: For straight cuts: use a circular saw with an acrylic blade. For curves or detailed work: a CO₂ laser cutter is best. Avoid cutting with regular woodworking tools without proper setup to prevent chipping or melting.

Q5: Can these sheets be used outdoors?
A: Yes. Cast acrylic is UV-resistant and weather-durable. It's commonly used for outdoor signage and protective covers.
