It is all about stopping the rainwater from penetrating the metal roof panels. The outer part of the roof can be made of metal sheets, of course, but rainwater mainly enters the metal roof through overlaps or joints from the inside. To get a leakage-free effect, sealing washers are installed at screw holes, and hidden fixing is used for the installation. At panel overlaps, sealant or welding is applied. Our prefab workshop buildings have the concept of using single-piece panels to solve the problem of partitions and provide tight waterproofing at all joints.
(1) To enhance the resistance to fire, the load-bearing steel parts of the prefabricated workshop building are covered with fire-retardant coatings by spraying. The specific approaches are mostly divided into types of thin-coat and thick-coat.
(2) Fire-retardant paint is a flame-retardant coating. In comparison with regular paint, the specialized foamed fire-retardant paint has a significantly higher ignition point even after air drying when exposed to fire, thus it has certain fire-retardant properties.
(3) The external surface of the prefabricated steel workshops is covered with one more layer of the outer cladding. The main research methods are widely varied: cast-in-place concrete, external masonry blocks, fire-resistant boards, felt-like flexible insulation material cladding, and spraying.
Hot-rolled Q345B H-beams, columns dimension 200×200-400×400mm, beam span ≤12m.
The prefabricated steel workshops conform to ISO 9001 standards, and a load calculation report serves as proof.
Disassembly is facilitated by bolted connections, which are also ideal for warehousing/logistics that are upgrading.
Standard orders will be delivered within 10 days; galvanized orders will take 5 days longer.
Equipment platforms, multi-layer mezzanines, uniformly distributed load of not less than 5 kN/m².
Hot-dip galvanizing (zinc layer thickness ≥ 120μm), fluorocarbon coating, and weather resistance of up to 32 years.
Zhongda has more than 2 decades of experience in the prefab metal garage building industry, has managed over 300 projects, and the factory has an annual production capacity of 60,000 tons. Moreover, its internal manufacturing equipment is of the highest quality and covers all the most advanced categories on the market, thus providing the best possible guarantee to customers from the ground up. The flexible beam span of prefab metal garage buildings can be up to 12 meters.
Besides, our prefab metal garage buildings and other constructions are all built on a bolted connection plan, thus the on-site installation as well as the future alteration works would be hassle-free.
Additionally, some special anti-corrosion measures are performed on metal prefab workshops, for instance, hot-dip galvanizing (zinc layer thickness ≥120μm) or fluorocarbon coating.
The load-bearing capacity of metal prefab workshops is optimized to be more than or equal to 5 kN/m2 uniform load-bearing capacity.
A leading distribution center for e-commerce: Storage capacity was increased by 200% through a 50,000 square meter multi-level platform. Order fulfillment time was also reduced by 30%.
An automotive parts manufacturer: Inventory management efficiency was elevated by 40% through a custom-designed mezzanine combined with an automated retrieval system.
· Besides that, prefabricated workshops are widely used in steel fabrications as load-bearing frameworks for heavy steel engineering projects.
· Workshops of open-hearth furnace, roughing mill, and blast furnace in metallurgical plants;
· Casting workshops, hydraulic workshops, and forging workshops in heavy machinery plants;
· Berth workshops and assembly workshops of shipyards and aircraft manufacturing plants;
· Various large-span workshops.

Shenyang Zhongda Steel Structure Engineering Co., Ltd., following the principles of "integrity, pragmatism, mutual benefit, and development," was named a base of the prefabricated building industry in Liaoning Province in July 2020.
The company has long been in-depth cooperation with well-known domestic design institutes and universities, and is a participant in many industry standards and specification compilations. The company has a reasonable talent structure and comprises a great number of management backbone personnel and skilled workers.
The company has many well-known domestic and foreign equipment manufacturers and material suppliers as its long-term and stable cooperative partners and is equipped with large-scale specialized equipment such as dry-tonnage presses, large roller mills, and 3D CNC planar drilling machines.
It has also built the biggest steel structure processing workshop in Northeast China in terms of lifting capacity. With its top-notch processing conditions and strength, it has become a qualified supplier and a strategic partner of major engineering bureaus of central enterprises such as China State Construction Engineering Corporation, China Railway Group Limited, and China Communications Construction Company.
