1. laboratory

We have been committed to the development and application of metal building technology, continuous optimization and upgrading of our products, to provide customers with more excellent green building.

Metal R & D Center has a "metal building envelope system laboratory", an area of nearly 1,000 square meters, with advanced research and development equipment, focusing on metal building product technology research and development, experiment and system integration, has successfully won dozens of patents and Certification, is "China Construction Metal Structure Association metal roofing system designated testing laboratory."

At the same time, we carry out the coating, plating, the overall program and the structural strength of the metal building envelope system, the wind exposed, durability, water tightness test, to provide customers with comprehensive technical advice and program verification services.

2 standard accessories

The essence of steel construction and containment systems is the factory prefabrication, site assembly, standard parts of various parts is to achieve the basic means of prefabricated assembly. To ensure the applicability, versatility and reliability of the building envelope system, more than 20 kinds of special fittings, conversion parts and standard supports have been developed. Through a reliable, clever connection to achieve a roof in the end, the overall slide, the side of the connection, rigid waterproof, never the risk of leakage purposes.

All the common parts of Botech Steel are self-mold-fixed and fixed-molded. Bolts, self-tapping screws and water-proof butyl cement are adopted for all parts. After checking calculation practice, unified standards and unified methods are adopted to ensure foolproof.

3.System patents

Steel building exterior wall housing complete sets of integrated products, steel products is the core of Bo Tai Steel. In the case of customer demand Botou Steel, the industry also conducted integrated product sales. Botai on several sub-system products through the fine manufacturing construction, the perfect combination of the overall prefabricated assembly to achieve the installation of reliable results.

Gable node system.

The metal sliding roof and the daughter wall gable node waterproofing system of the invention are characterized in that the two sliding brackets are fixed on the special edge sealing angle steel and the hidden gutter and the internal blister plate are connected with the upper and lower two sliding brackets Connection, so that the entire roofing system that is close and firm, but also relative to the roof purlins and the appropriate sliding wall panels to solve the pan between the grate plate and gable support, due to poor sliding joints caused by tearing leakage defect.

The special design of the hidden gutter, the internal floodplain and the floodwater diverting elements does not have any nail holes in the roofing panel and will not be soaked in rainwater during the rainy season nor will it soak in the winter due to the melting of snow. Therefore, It greatly reduced the number of freeze-thaw cycles, which is greatly improved water resistance.

In the sliding roof waterproofing system of the present invention, the water will fall on the built-in concealed sliding gutter even if the inner flashing water under the daughter's wall leaks at the longitudinal lap, and then discharged to the gutter of the building roof So as to completely solve the problem of leakage caused by the aging of the mortar at the nail hole of the roofing panel and greatly improve the service life of the building and realize the rigid waterproofing of the sliding roofing connection system.

Main features: Bracket conversion; Side connection; Rigid waterproof; Built-in gutter; Overall sliding.

Indoor Gutter Node System

The main object of the present invention is to provide a method of connecting a gutter with a natural slope and a method of connecting a metal roof to a gutter and a new waterproof cornice flap that fully satisfies the requirements of a metal roof panel in a gutter cornice Department of the solid, anti-slip, waterproof, tightness and plate installation pattern, standardization.
