Frequently Asked Questions

Aluminium shims offer higher durability and precision for heavy industrial loads, while plastic shims are easier to cut and ideal for lighter furniture or door adjustments.

Measure the gap precisely. It is often better to start with thinner shims and stack them or use adjustable wedges to achieve a perfect, snug fit without forcing components.

Plastic and composite shims are generally weather-resistant. Metal shims like aluminium or steel should be coated or treated to prevent corrosion if used in damp outdoor environments.
