Polyurethane composite board is recognized as the best heat insulation and energy-saving material in the world. It has been widely used in large industrial plants, exhibition halls, gymnasiums, cold storages, purification workshops, animal husbandry, edible fungi and other industries.

The material selection and processing of polyurethane board strictly follow the national and industrial environmental protection standards. use   In the process, the plate is not easy to breed bacteria and parasites, and is suitable for various complex situations in the cold chain industry   And stringent environmental requirements. Cold storage insulation system with proprietary plate type air tight structure technology   The cold storage body is organically connected to achieve absolute air tightness and save energy consumption   30%, greatly reduced   Low operating costs.

Five product series meet the diverse needs of customers, and can produce more than 30 types of wall panels and roof panels

Hongli curtain wall system with metal surface thermal insulation and decoration is an integrated composite material with multiple functions; Should   When the system meets or exceeds the relevant national standards, designers can choose a variety of materials and use a variety of colors to interpret their own   Own design language; The use of a single system provides a one-stop solution for building facade insulation, fire prevention and durability   Plan to provide better protection for people and property.

The prefabricated integrated house takes the standard box as the basic unit. Like building blocks, it can be combined in various forms horizontally or vertically. The spatial layout is flexible and the function is prefabricated, realizing the diversification of use functions and application fields.
