In steel structure project design, procurement and construction, accurately interpreting steel grades is a key aspect of ensuring material compliance and building engineering safety.
China Steel Grade System
China's steel grading system is based on the combination of "Pinyin letters + Chemical element symbols + Arabic numerals," with each character corresponding to specific material properties. | Steel Grade | Corresponding Standard | Tensile Strength (MPa) |
| Q235 | GB/T 700 | 235 |
| Q345 | GB/T 1591 | 345 |
| A36 | A572Gr.50 | 250 |
| A36 | ASTM A36 | 250 |
| A336 | ASTM A572 | 345 |
Carbon Structural Steel/Low Alloy High Strength Structural Steel (Most Common)
Core format: Q + Yield Strength Value + Quality Grade Symbol + Deoxidation Method Symbol
Q: Derived from the first letter of "yield strength", representing the steel's primary indicator as yield strength.
Numerals: Represent the yield strength value (in MPa), such as Q235 representing a yield strength ≥235MPa, Q345 representing ≥345MPa.
Quality Grade Symbol: Ranges from A to E, corresponding to impact toughness requirements from low to high (Grade A does not require impact testing, while Grade E requires impact testing at -40°C). For example, Q345D indicates low alloy steel with a yield strength of 345MPa and Grade D quality.
U.S. Steel Grade System: ASTM/SAE
Carbon Steel and Alloy Structural Steel (SAE/ASTM General Use)
Core format: Four-digit number + (letter suffix)
First Two Digits: Represent the steel type and main alloy elements, acting as a "classification code." Common correspondence is as follows:
10XX: Carbon steel (no alloy elements), such as 1008, 1045.
15XX: High manganese carbon steel (manganese content 1.00%-1.65%), such as 1524.
41XX: Chromium-molybdenum steel (contains chromium 0.50%-0.90%, molybdenum 0.12%-0.20%), such as 4140.
43XX: Nickel-chromium-molybdenum steel (contains nickel 1.65%-2.00%, chromium 0.40%-0.60%), such as 4340.
30XX: Nickel-chromium steel (contains nickel 2.00%-2.50%, chromium 0.70%-1.00%), such as 3040.
Last Two Digits: Represent the average carbon content (measured in ten-thousandths), such as 1045 representing carbon content ≈0.45%, and 4140 representing carbon content ≈0.40%.

Undertaking steel structure projects requires corresponding qualifications.
At present, China's steel structure engineering professional contracting qualification is divided into first, second and third grades, of which one is the highest and three is the lowest.
For specific steel structure engineering projects such as steel structure workshops, prefab steel structure offices, etc., what qualifications are needed?
There are clear provisions in China construction qualification standards, and the scope of contracted projects corresponding to different qualifications is different:
First-grade qualification enterprises can undertake steel structure projects: steel structure height of more than 60 meters, span of more than 30 meters, lattice structure, grid structure short side span of more than 50 meters, single steel structure engineering steel structure total of more than 4,000 tons, single building area of more than 30,000 square meters.
Second-grade qualification can undertake steel structure projects are: steel structure height below 100 meters, single span of steel structure below 36 meters, short side span of lattice shell and grid structure below 75 meters, total steel structure weight of single steel structure project below 6,000 tons, and single area below 35,000 square meters.
Third-grade qualification can undertake the following projects: steel structure height is less than 60 meters, single span of steel structure is less than 30 meters, short side span of lattice shell and grid structure is less than 33 meters, total weight of single steel structure project is less than 3,000 tons, and single building area is less than 15,000 square meters.

Roof slope of a steel structure factory is an important architectural element, which not only affects exterior appearance, but also its functionality and service life.
1. The significance of the roof slope
The roof slope of steel structure workshop is mainly for drainage and waterproof. The appropriate slope can ensure the smooth discharge of rainwater and snow, prevent water accumulation from damaging the roof, and ensure the safety inside the factory. In addition, the roof slope can also enhance the appearance and the overall architectural image of the workshop.
2. Design principles
When designing and constructing a steel structure workshop, the local geographical environment, climatic conditions, rainfall and construction requirements will be considered comprehensively to determine the appropriate roof slope.
Generally speaking, the roof slope should be set according to local rainfall. In rainy areas, the roof slope should be larger to ensure rapid drainage and prevent water accumulation. Otherwise, it would be reduced to save construction costs.
At the same time, the roof slope should also take into account the discharge of snow water. In areas with heavy snowfall, a larger slope will be selected to facilitate the rapid discharge of snow water. In areas with less snowfall, a smaller slope can be selected.
3. Calculation method
It is mainly calculated according to roof area and rainfall. Generally speaking, the larger roof area, the larger the slope required. At the same time, the slope of the roof and the design of the drainage system can be adjusted according to the amount of rainfall.
In short, the roof slope of a steel structure workshop is an important building element, which is related to the functionality and service life of the workshop. Various factors need to be considered comprehensively to determine the appropriate roof slope to ensure the safety, practicality and beauty of the factory.

Fast construction speed: Steel structure workshop can be fabricated quickly because steel components can be prefabricated in the factory and only need to be bolted on construction site, which shortens the construction period.
Eco-friendly and sustainable: Steel can be recycled and reused, and the noise and dust generated during the construction process are relatively small.
High strength and light weight: Steel structure workshop has high strength and can withstand large loads. At the same time, their weight is relatively light, which can reduce the cost and construction difficulty of civil engineering works.
High space utilization rate: The space utilization rate of steel structure workshop is high, because the steel structure can arrange the space flexibly, making the space of the workshop more flexible and open.
Easy maintenance: Steel structure workshop has good anti-corrosion and fire-proof properties, which can reduce maintenance costs and difficulty.
In summary, modern industrial workshop design and warehouse construction prefer steel structure building solution because of its fast construction, environmental sustainability, high strength, light weight, high space utilization and easy maintenance.

First, confirm the land is industrial land purpose, if it is not legal industrial land, it will be allowed to build steel structure workshop on it.
Second, if building a steel structure workshop on leased land, it needs to specify who will owns the building after term of lease. Or you can choose to renew this workshop building lease.
Third, take the workshop procedures to local Land Administration Bureau to handle the relevant formalities, you need to get certificate for the right of land usage first, and then a planning permission.
Fourth, go to local environmental protection department and construction department to apply for documents and certificates. A construction permit is required before starting steel structure workshop construction.
