Pricing for solid wood cabinet doors depends on the wood species used.

A steel door is a durable, secure, and low-maintenance option commonly used in both residential and commercial buildings. Constructed with a steel outer layer and often filled with insulating materials like polyurethane or honeycomb core, these doors offer excellent strength, fire resistance, and energy efficiency. Steel doors are ideal for exterior use due to their ability to withstand harsh weather, resist warping, and provide enhanced protection against forced entry. Available in a variety of finishes, colors, and designs, they can also be customized to match different architectural styles while ensuring long-lasting performance and safety.
