Strand Woven Series

Fastener Splicing Outdoor Heavy Strand Woven Bamboo Flooring

The Fastener splicing outdoor heavy strand woven bamboo flooring represents a technical advancement in high-density exterior surfacing materials. This product utilizes a strand woven bamboo manufacturing process, where bamboo fibers are compressed under intense hydraulic pressure to achieve a density exceeding 1.2g/cm³. The integration of a specialized fastener system allows for efficient installation while accommodating the natural expansion and contraction cycles of the material in exterior environments.

Structural Integrity and Material Composition

The core of this outdoor heavy bamboo decking consists of crushed bamboo strips that have undergone a thermal treatment process at 200°C. This carbonization process removes starch and sugars from the bamboo fiber, significantly reducing the moisture absorption rate and preventing the growth of fungi or wood-decaying organisms. The resulting high-density bamboo boards exhibit mechanical properties comparable to tropical hardwoods, specifically regarding Janka hardness and modulus of rupture.

Carbonization temperature: 200°C · Moisture content controlled: 8%-12%

Key Technical Features

Spliced Fastener System: Designed to minimize visible surface fixings, ensuring a seamless aesthetic while maintaining structural stability.

High Dimensional Stability: The thermal modification and resin infusion processes limit volumetric swelling and shrinkage in varying humidity levels.

Environmental Resistance: Formulated for commercial outdoor bamboo flooring applications, offering resistance to UV degradation and surface erosion.

Slip Resistance: The surface profile is engineered to meet safety standards for public walkways and poolside installations.

Installation and Maintenance Protocol

For optimal performance of spliced heavy bamboo flooring, it is necessary to utilize a joist system with a maximum spacing of 400mm. The fastener-based installation ensures consistent gapping for drainage and ventilation. Routine maintenance involving the application of a water-based exterior oil is recommended every 12 to 18 months to preserve the color density and surface integrity of the bamboo timbers and beams used in the assembly.

Frequently Asked Questions

What makes the fastener splicing system more effective than traditional top-down screwing for outdoor bamboo?

The fastener splicing system provides a mechanical advantage by allowing the boards to expand and contract along their longitudinal axis without putting direct stress on the screw heads. This prevents surface cracking and board warping. As a professional manufacturer, Ningguo Kuntai Bamboo and Wood Co.,Ltd. utilizes advanced precision milling to ensure these fastener grooves meet tight tolerances. Furthermore, Ningguo Kuntai Bamboo and Wood Co.,Ltd. is the holder of a US patent for outdoor bamboo decking (No. US11148318), specifically authorized as a manufacturer and exporter in China for these innovative decking solutions. Our modern 30,000 square meter factory in Anhui ensures that every spliced board adheres to these patented structural requirements.

How does this product perform in high-moisture or tropical outdoor climates?

This flooring is specifically engineered for severe exposure. By utilizing strand woven bamboo technology, the fiber is saturated with phenolic resin and compressed, making it nearly impermeable to water compared to traditional timber. Ningguo Kuntai Bamboo and Wood Co.,Ltd. is located in Ningguo, Xuancheng City, Anhui Province, known as the "Bamboo Village," where the local raw materials are selected for their maturity and fiber strength. Our facility, operating under the "Huihuang Bamboo" brand established in 2002, holds FSC, CE, SGS, and ISO9001/ISO14001 certifications, ensuring that our bamboo wall-cladding, flooring, and bamboo garden furniture maintain structural integrity even in humid or coastal environments.

Can these bamboo panels be used for architectural applications other than flooring?

Yes, the material's high density and durability allow for versatile architectural use. KUNTAI is a professional manufacturer of not only flooring but also bamboo wall-cladding and siding, bamboo panels, plywood, bamboo boards, and even bamboo ceiling and roof systems. The technical properties of our heavy strand woven material make it suitable for any exterior application requiring a high-load capacity and weather resistance.
