Jing Shing Industry (JSI) uses a material that contains 40~60% high-density polyethylene (HDPE) and 60~40% wood fiber, producing environmentally-friendly, plastic-wood composites called JPWs which strictly adheres to the Restriction of Hazardous Substances (RoHS) rule. JPW’s retain the strength of wood, combining the elasticity and impact resistance of plastic, thereby incorporating the most desirable physical properties of both wood and plastic into a single composite material. JSI makes three kinds of JPW materials for the assembly of easy-to-build wood-style homes which are as follows:
(A) Light Wood (LW): The density is regulated within 70% ~ 95% of light wood — used in regular plates.
(B) Polycore Wood (PW): Made with two or more layers of compounds — used in thicker plates.
(C) Metal-Polycore Wood (MPW): Since plastic-wood composites are not quite as strong as natural wood, a piece of metal is inserted into the center of the polycore wood piece for extra strength — used in normal pillars and beams.
JSI processes the pre-fabricated JPW materials at the factory site, based on a specific design, then ships the materials to the construction site. All fastenings are complete do-it-yourself, and assembly instructions may be provided upon request. By utilizing bolts and screws for assembly not only makes the construction simpler, but also streamlines the disassembling (for expansion purposes, tear-down, mobility or modification). This easy, hands-on (do-it-yourself) method is extremely beneficial where labor is readily available, i.e. devastated areas affected by floods, earthquakes, storms or other natural disasters, where immediate shelter is needed yet, the materials may not be at hand. JPW may solve the problem because manpower can be easily deployed or self-supplied, kits are pre-fabricated and parts included and then send to the devastated area.
