  • Who Uses Prefabricated Building?

    The short construction time, high quality, and cost savings make prefabricated buildings desirable for many industries. Plus, the quality of prefabricated steel building is becoming better year over year. Prefabrication is more about how the building was made rather than the kind of building it is. Therefore basically any professional company can make use of a prefabricated steel structure building.
    Some industries may need a turn-key construction method due to a variety of limitations. For instance, they may be on a tight budget. Additionally, they may need the space to be up and running very quickly or need uniformity in structure that prefabrication provides. For those reasons, the top industries that have been turning to prefabricated buildings are:
    Industrial Park
    Warehouse Steel Structure
    Hangar
    Factory/Plant
    Logistics and Distribution Warehouse
    Commercial Retail

  • What's Shear Key in Steel Structure?

    In steel structure construction, the column base connection is the critical component connecting the superstructure with the concrete foundation. It needs to safely and reliably transfer various loads from the superstructure: vertical compression, uplift tension, bending moment, and horizontal shear.
    When the horizontal shear force is significant, and the friction resistance between the column base plate and the concrete foundation contact surface alone is insufficient to resist it, a key small component becomes indispensable—this is the Shear Key.

    What is a Steel Structure Shear Key?
    A shear key, as the name implies, is a steel connection component specifically designed to resist and transfer horizontal shear forces. It is essentially a short steel member.

    Where does it install?
    Typically welded or anchored to the base plate of a steel column (or other load-bearing members like equipment supports), with its lower end embedded in the cast-in-place concrete foundation or concrete structure below.

    What are common types?
    Headed Studs: Like short nails with a larger head, factory-welded to the base plate. The most widely used type, with a high degree of standardization.
    Short Sections of Structural Steel: Such as angle steel, T-sections, channel sections, or I-beam segments. Used for heavy-duty structures or equipment foundations with very high shear forces, offering large load-bearing capacity and stiffness.
    Shear Plates: A thick steel plate with holes or anchor bars, pre-embedded in concrete and welded to the column base plate.

    What are characteristics?
    It is not an ordinary anchor bolt. Anchor bolts primarily resist uplift forces and fix the position, whereas the core mission of the shear key is to handle horizontal shear forces. It acts as the "stabilizing pillar" preventing sliding in structural safety.

    In short: A shear key is a steel "stop block" or "pin" rooted in the concrete and welded to the steel column base, specifically designed to prevent horizontal sliding between the steel structure and the foundation.

  • Why Is the Steel Called “A36” in the U.S. and “Q235” in China?

        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%.
     

  • How To Select A Qualified Steel Structure Manufacturers & Construction Suppliers?

    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:

  • What's the General Slope Of Warehouse Steel Structure For Factory?

    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.
