It is a typical multi-layer composite structure, consisting of surface fibers, primary backing, secondary backing, and possibly additional functional layers.

High-quality commercial carpets must obtain indoor air quality certification (such as GREENGUARD Gold) to ensure low VOC emissions.

Thoroughly clean the base layer, removing all dust, oil stains, paint residues, and other pollutants that may affect adhesion.

Precise layout must be carried out before laying to ensure that the carpet texture direction is consistent (usually facing the main light source).

Block carpets are mostly laid using an adhesive-free method (with movable backing), relying on close splicing and edge sealing around the perimeter for fixation, making it convenient for local replacement.
