From Factories to Bridges: Steel Structure Solutions Across Industries

How are steel structure projects carried out? Simply put, it is a three-step process of deepening design, factory prefabrication, and on-site assembly to transform steel into a building skeleton with strong load-bearing capacity. The advantages of steel structure buildings are high strength, light weight, fast construction, good seismic resistance, and 100% material recycling. The key to construction lies in the precision of deepening design and the safety control of on-site lifting. A conventional steel structure factory building takes approximately 45 to 90 days from detailed design to main completion. If you are looking for a trustworthy steel structure company,Guangdong Hongsheng Steel Structure Group Co., LtdWe are a large-scale steel structure engineering construction and steel structure material production source manufacturer at home and abroad, with branch offices both domestically and internationally, providing you with one-stop services from materials to construction. Below, we explain practical solutions for steel structure engineering from three dimensions.

Firstly, material selection and anti-corrosion scheme for steel structures in the Pearl River Delta region

The Pearl River Delta region experiences high temperatures and humidity throughout the year, with severe salt spray corrosion in coastal areas. Many customers tend to only focus on price when choosing steel structural materials, but overlook the impact of the environment on the lifespan of steel. We strongly recommend adopting in cities such as Huizhou, Dongguan, and Shenzhen in GuangdongSteel grades Q355B and aboveAnd equipped with hot-dip galvanizing or fluorocarbon spraying processes. The thickness of hot-dip galvanized layer needs to reach 85 microns or more to effectively resist the erosion of oceanic climate.

The specific material selection plan is as follows:

• Roof and wall system: Aluminum zinc coated profiled steel plates with a thickness of not less than 0.5mm are used to ensure typhoon resistance.

• High strength bolt connection pair: 10.9 grade large hexagon head bolts must be selected and subjected to torque coefficient retesting.

• Fireproof coating: According to the fire resistance rating of the building, the thickness of thin fireproof coating is controlled between 2.5mm and 4.5mm.

This refined material selection scheme can ensure that steel structure buildings can be used for more than 30 years without major repairs in the complex climate of the Pearl River Delta, which is a technical guarantee that ordinary workshop style processing plants cannot provide.

Secondly, rapid construction plan for large-span steel structure factory buildings

We adopt a model of "factory prefabrication rate of 85%+on-site assembly construction" to address the schedule concerns of manufacturing customers. Traditional concrete structures require on-site curing, while steel structural components are all cut, welded, drilled, shot blasted, and rust removed in the factory. After arriving at the site, only bolt connections and local welding are required.

Taking a smart equipment manufacturing base in Foshan that we undertake as an example, the factory has a single span of 36 meters and a total construction area of approximately 32000 square meters. We use BIM technology for collision detection, accurately numbering the components to each purlin. During on-site construction, 2 sets of 80 ton truck cranes and 1 set of 50 ton crawler crane were deployed, using only58 daysThe installation of the main steel structure was completed 12 days ahead of schedule. During the construction period, we assigned dedicated safety officers to supervise and ensure zero accidents during high-altitude operations. This rapid construction capability saves project owners a lot of rental costs and labor expenses.

Thirdly, the plan for adding floors to existing buildings and renovating bridge steel structures

Many old factories in Pearl River Delta cities are facing the demand for capacity expansion, but land resources are tight. We provide a mature a solution for adding floors to existing buildings, which involves implanting chemical anchor bolts on the original concrete columns, adding steel beams and columns, and achieving the goal of "asking for space from the sky". In a food processing plant project in Shanwei, we completed the addition of a two-story steel platform without affecting the production on the first floor, with an additional area of 1800 square meters. The construction process only generated slight noise.

For bridge steel structures, we use orthotropic steel bridge deck technology, combined with high-precision CNC cutting equipment, to ensure that the fusion welding quality between the U-ribs and the deck meets the first-class weld seam standard. In the Shenzhen pedestrian overpass project, we were responsible for a steel box girder section weighing 240 tons. We used segmented transportation and on-site overall lifting technology to complete the closure overnight, minimizing the impact on urban traffic.

Local case: Huizhou Zhongkai High tech Zone Electronic Factory Project

Last year, we built a steel structure dust-free workshop for a precision electronic component enterprise in Zhongkai High tech Zone, Huizhou. After 65 days of construction, it was completed and the customer praised the flatness and perpendicularity during the inspection. The factory building is 120 meters long, 48 meters wide, with an eaves height of 9 meters, and is equipped with a 10 ton crane inside. We use variable cross-section H-shaped steel as the main beam, with column spacing controlled at 8 meters, which not only meets the flexibility of process layout but also reduces steel consumption. Visually, we have chosen ivory white polyurethane sandwich panels, combined with dark gray edging, making the entire factory look very grand, completely overturning the stereotype of traditional factory simplicity. The owner provided feedback later that due to the large span of the steel structure, the utilization rate of internal space is 15% higher than that of the adjacent concrete factory, making it extremely cost-effective.

Having been deeply involved in the field of steel structure construction for many years,Guangdong Hongsheng Steel Structure Group Co., LtdAlways adhere to technology driven service. We have the first-class qualification for steel structure engineering professional contracting issued by the Ministry of Housing and Urban Rural Development, as well as an intelligent steel structure production line with an annual output of 100,000 tonnes. We can provide full process services from drawing deepening, material procurement, processing and manufacturing to on-site installation for industrial plants, high-rise buildings, bridge venues, and special equipment supports.
