I-Joist is a New Wooden Engineering Structural Component. It refers to the solid wood or LVL used as the upper and lower flange, and the plywood structural plate bonding, specifications and performance of stable bearing structural members. The I joist is made up of two main parts: Flange and the web. The upper and lower Flange, which is made up of solid wood or LVL. The second part is the intermediate Web usually made of OSB board. The web and flange are connected together with high-quality adhesives to form an ‘I’ shape. The web of the I-joist can be cut open to accommodate wires and pipes.

Advantages
It can be widely used in horizontal formwork system, vertical formwork system (wall mold, column mold, hydraulic climbing mold, etc.), variable arc formwork system and heterosexual formwork and other formwork system.
Woodworking beam straight wall template for loading and unloading, convenient assembly. With a certain range and degree, it can be assembled into a variety of sizes of templates, flexible application. Mold plate stiffness, length and height are very convenient and the maximum of a template can be poured more than 10 meters. Because of the light quality of the template material, the whole template is much lighter than the steel template when assembled.
The system product parts has high degrees of standardization, good reuse and meets the requirements of environmental protection.
