" Fifteen Five Year Plan; The target for steel use in steel structures is 150 million tons: Under increased policy measures

   " Fifteen Five Year Plan; The target for steel use in steel structures is 150 million tons: Under increased policy measures, how should factory owners choose structural solutions? The steel structure industry is entering a clear policy window period. " Fifteen Five Year Plan; During this period, the national steel consumption target for steel structures was set at 150 million tons, with prefabricated buildings, industrial plants, and warehousing and logistics facilities becoming key penetration scenarios. For owners preparing to build, expand, or renovate their factories, the choice of structural scheme is no longer just about; How much does it cost per square meter; The issue is related to approval compliance, construction cycle, later expansion, and full lifecycle costs. Guangdong Hongsheng Steel Structure Group Co., Ltd. has been focusing on the field of steel structure construction for many years. It is a large-scale steel structure engineering construction and steel structure material production source manufacturer at home and abroad, with branches both domestically and internationally. The consultation hotline is 400-931-0660. Starting from policy orientation, this article breaks down several key issues that factory owners need to clarify in structural selection.

1. What does the target of 150 million tons mean for factory owners?

The increase in steel consumption target for steel structures is driven by three factors: firstly, the evaluation standards for prefabricated buildings have been implemented in various regions, and the proportion of industrial plants using steel structures continues to rise.

; Secondly, the price of steel is relatively stable, and the gap between the comprehensive cost of steel structure factories and concrete solutions is narrowing; The third is the pressure of project schedule, and manufacturing projects pay attention to it; Start construction upon land acquisition, and put into operation upon completion; The construction speed advantage of steel structures is amplified.

For homeowners, there are three direct changes brought about by policy intensification:

• Smoother approval process: In the evaluation of prefabricated building indicators and green buildings, steel structure schemes are more likely to meet requirements, and there is less resistance to scheme argumentation during the application stage.

  .

• The supply side is more mature: Steel structure material manufacturers have sufficient production capacity, improved standardization of components, and enhanced controllability of delivery times.

  .

• Competition is more differentiated: There are many steel structure engineering companies in the market, but there are not many source manufacturers with integrated design, production, and construction capabilities. Choosing the wrong partner brings rework costs far higher than the price difference..

In other words, policies have pushed steel structures to the mainstream position of factory construction, but the difficulty of decision-making for owners has not decreased. Instead, it is more important to see the technical parameters and implementation capabilities behind the structural scheme.

2. How to choose the structural scheme of the factory building: four judgment dimensions

There is no steel structure scheme for the factory building.; Universal Optimal Solution; Only '; Solution for matching working conditions;. Owners can filter from the following four dimensions.

1. Span and column spacing determine the main structural form

For conventional factory buildings with a single span of less than 24 meters and column spacing of 6 to 9 meters, portal frames are a more economical choice;

; If the span exceeds 30 meters, there is a need for crane hoisting, or a large space production line layout, a lattice column, truss, or grid system needs to be used. Owners should first clarify the requirements for clearance, column grid, and crane tonnage in the production process, and then discuss the structural form to avoid secondary design caused by changing the process after finalizing the plan.

2. Load conditions determine the amount of steel used

Roof loads, snow loads, hanging loads, and equipment vibration loads all directly affect the section of components and the amount of steel used.

. The Pearl River Delta region also needs to focus on the wind load values under typhoon conditions. The basic wind pressure should be taken according to local regulations, and the roof system should undergo wind resistance verification. The lower the amount of steel used, the better. Solutions below the reasonable range often cut corners and materials in nodes and support systems.

3. Corrosion and fire prevention determine the maintenance cost in the later stage

Corrosion prevention of steel structures is a long-term issue in the high temperature and humidity of Lingnan region.

. Conventional factories can adopt a coating system of primer and topcoat, while workshops with damp or corrosive media should increase the coating grade or use hot-dip galvanized components. In terms of fire prevention, the type and thickness of fireproof coating for steel components are determined according to the fire resistance rating of the building. This cost is easily compressed in the quotation, and the owner needs to clarify it in the contract.

4. Reserve for expansion and renovation

Manufacturing production lines are frequently adjusted. Whether the factory structure has reserved expansion ends, whether the roof has reserved photovoltaic loads, and whether the column base nodes are easy to reinforce should all be confirmed during the design phase.

. One time design is more cost-effective than later reinforcement and renovation.

Third, the difference behind the quotation: Why is there such a big price difference for the same steel structure factory?

The most common confusion for factory owners is that the quotations of several steel structure engineering companies differ by 20-30%, and the drawings look similar.

. Differences are usually hidden in the following aspects.

• Material source: The source manufacturer directly supplies steel and the trader resells it, with different procurement costs;

  ; The thickness of the galvanized layer on the sheet and the brand of the color steel plate substrate will both affect the unit price.

• Deepening design capability: The deepening quality of node details and component processing drawings directly determines whether the on-site installation is smooth, and on-site modifications caused by inadequate deepening are implicit costs.

  .

• Manufacturing accuracy: The factory level of component cutting, welding, rust removal, and painting affects installation efficiency and later maintenance.

  .

• Construction organization: Whether there is a self owned installation team and whether there is project experience in similar working conditions determines whether the construction period can be fulfilled.

  .

Guangdong Hongsheng Steel Structure Group Co., Ltd. has been focusing on the field of steel structure construction for many years, with integrated capabilities in steel structure engineering construction and steel structure material production. From deepening design, component manufacturing to on-site installation, a closed loop is formed to reduce communication losses in intermediate links.

. For factory owners, choosing such source manufacturers provides higher transparency in pricing and clearer responsibility interfaces. The consultation hotline is 400-931-0660, and the official website www.hstteelwork.com provides access to engineering cases and product systems.

IV. Owner's Decision List: Six things that must be confirmed before signing the contract

Put the structural scheme at the contract level and suggest that the owner confirm each item:

1. Whether the structural calculation sheet is prepared according to current specifications, and whether the values of wind and snow loads are consistent with the project location;

   ;

2. Does the steel quantity list specify the specifications, material grades, and plate thickness of the main components?

   ;

3. Does the anti-corrosion coating system clearly specify the coating type, number of coats, and dry film thickness?

   ;

4. Whether the type, thickness, and fire resistance limit of fireproof coating are included in the contract;

   ;

5. Whether the plate type, substrate thickness, and galvanized layer content of the roof and wall enclosure system are specified;

   ;

6. Is the schedule, acceptance criteria, and warranty period clear, especially regarding the warranty responsibilities for roof waterproofing and structural safety?

   .

These six items have been confirmed clearly, which can basically avoid most of the later disputes. The value of a structural scheme lies not in the appearance of the drawings, but in the fact that every parameter can be implemented, accepted, and traced.

V. Conclusion

; Fifteen Five Year Plan; The improvement of steel targets for steel structures is beneficial for factory owners, but the benefits only belong to those who choose the right plan and partner. The structural form should match the process, the amount of steel used should match the load, anti-corrosion and fire prevention should match the environment, and the quotation should match the responsibility interface. Think about these four things clearly before discussing the price.
