Core Advantages

Structural Stability

The thermal-treatment process modifies the bamboo's molecular structure, resulting in a low expansion coefficient and minimal warping under direct sunlight.

Weather Resistance

Formulated with UV-stabilized resins, the material maintains its structural integrity and color density when exposed to prolonged ultraviolet radiation and heavy precipitation.

Slip Resistance

The dual-stripe profile increases the friction coefficient, meeting safety standards for commercial and residential outdoor walking surfaces.

Eco-Friendly Composition

Utilizing rapidly renewable bamboo resources, this flooring serves as a carbon-sequestering alternative to slow-growing hardwoods.

Installation and Maintenance Guidelines

Subfloor Preparation

The installation site must have a minimum slope of 1-2% to ensure effective water drainage beneath the joist system. A solid foundation, such as concrete or a specialized metal frame, is required to prevent subsidence and maintain a level surface over time.

Gap Requirements

End-to-End Gaps: 3mm to 5mm between short ends for longitudinal thermal expansion

Side-to-Side Gaps: 5mm to 6mm between parallel boards via hidden fastening clips for airflow and drainage

Storage Conditions

Prior to installation, boards should be stored in a dry, ventilated area, stacked flat on pallets. Avoid direct exposure to rain or soil contact before the material is properly secured to the joist system. Allowing the material to acclimate to local humidity levels for 48 to 72 hours is recommended.
