1.The main frame adopts a one-time molding process, with good mechanical properties, which can transfer the carrying capacity of all parts of the surface of the greenhouse to the base, without forming concentrated stress, thus improving the overall strength;
2.It has good corrosion resistance and weather resistance. In the environment of high temperature and high oxygen content in the greenhouse, and in the environment of high temperature and low temperature in the rain and snow exposed to ultraviolet light, its mechanical properties and surface structure will not change significantly, and its service life is more than 30 years;
3.High strength, can reach or more than the same cross-sectional area of steel toughness, specific gravity is only 1/4 of the steel, easy to install construction.

Polycarbonate Sheets and Polycarbonate Panels are perfect for hundreds of projects.

Polycarbonate Panels are the jack-of-all-trades for plastic sheets. Durable, versatile, and easy to work with, polycarbonate panels can be used in hundreds of custom projects. Patio and pergola coverings, skylights, custom greenhouses and other structures. We've even had customers use them for solar cookers and biomass generators. There is no limit to their use.

Polycarbonate panels are less expensive in comparison to almost any other plastic sheet, and they are easier to work with than glass or acrylic. Use polycarbonate panels for your next custom project.

The filling material is fireproof polyurethane, which has better fireproof and heat preservation effect than rock wool, and is lighter and more environmentally friendly.

HongBang Composites manufactures hand lay-up and filament wound FRP profile in all commercially available resin systems including: polyester, vinyl ester, furan, phenolic, and epoxy. Resin systems, as well as reinforcements, are tailored for specific applications. 

The design of any FRP profile must take into account many different factors. Corrosion allowances, operating pressure, vacuum, temperature, abrasion, flammability, and electrical conductivity are just a few of the characteristics that must be considered and addressed with proper choice of materials of construction. Mechanical design evaluates the strength of the FRP profile, the requirements for supports, thermal expansion compensation, burial loads, wind, snow and seismic considerations. Laminate analysis, and when required, finite element analysis is a part of the overall FRP profile design solution.

The system analysis is completed using conventional techniques, substituting appropriate physical properties for the fiberglass system specified. A typical Specification for fiberglass profile is also available from HongBang Composites.

FRP or Fiberglass reinforced thermoset plastic FRP structure is often the material of choice for corrosive process systems. This is due to a variety of factors, including:

• Customizable for a variety of applications
• Light weight (< 20% of steel, 10% of concrete)
• Excellent strength to weight (stronger than steel on an equal weight basis)
• Low coefficient of friction (>25% better than steel)
• Excellent dimensional stability
• Low thermal conductivity (saving insulation costs)
• Low long-term maintenance costs

An evaluation of life cycle costs of a system, including all of the above variables, often demonstrates significant cost savings for FRP structure vs. steel; with even greater cost savings over alternative alloy materials.

Self-developed FRP shutters got two Certificates of Utility Model Patent. One patent No is Zl 2007 2 0100630.1 for Fixed Shutters and the other is Zl 2007 2 0100631.6 for Movable Shutters.
