Frequently Asked Questions About SCM

At Piedmont Plastics, we offer high-quality SCM panels that are designed to meet a wide range of industrial, commercial, and creative needs. Below are answers to the most commonly asked questions about steel composite material.

SCM is a rigid panel made by bonding two thin layers of steel—typically galvanized or stainless steel—to a polyethylene (PE) core. This creates a strong yet lightweight sheet that combines the durability of steel with the versatility of plastic.

SCM consists of two thin steel skins bonded to a polyethylene (PE) core, while ACM is made with two thin aluminum skins bonded to a similar core. SCM is heavier, stronger, and magnetic receptive, while ACM is lighter and more corrosion-resistant.

Yes, SCM is magnetic receptive. This makes it a great option for applications like whiteboards, menu boards, and other surfaces that use magnets.

Yes. SCM panels have a smooth, coated surface that is compatible with direct digital printing, screen printing, and vinyl graphics.

SCM can be cut and fabricated using standard metalworking tools or CNC machinery. Piedmont Plastics offers custom cutting and fabrication services to meet specific project requirements.
