Did you know?
90% of steel structure construction errors come from incorrect design or production preparation.
In the industrial construction industry – where absolute precision is required – thorough inspection before putting into production at the factory is a mandatory step, helping to avoid a series of consequences such as:
- Increased material costs
- Detailed errors that are difficult to fix
- Delayed delivery progress
- Even having to… "remake the whole thing"
🎯 So, what factors need to be "examined carefully down to the millimeter" before starting to produce steel structures?
✅ 1.Detailed technical drawings – Must match 100%
Before cutting, welding, stamping or assembling, the technical drawing is the “compass” for the entire production process.
If the drawing is unclear, lacks parameters or is out of scale, no matter how modern the factory’s machinery is… it will “lose its way”.
📌 Need to check:
- Correct proportion, enough size
- Clearly note the material, connection, bolt position
- Have a general and detailed assembly drawing
👉 Professional suggestion: Apply BIM software to detect conflicts and discrepancies between architectural - structural - mechanical and electrical drawings before deploying to the workshop.
✅ 2. Material types & specifications
What kind of steel are you working with? Square steel? Profile steel? Plate steel? Does it meet ASTM, JIS, TCVN standards?
🎯 Wrong type of material will:
- Not meet tensile - compressive strength
- Cause deformation of the structure over time
- Difficult to assemble if the thickness is wrong
📌 Need to check:
- Steel grade, clear origin
- Material certificate (Mill Test Certificate)
- Thickness - length - allowable deviation in curvature
✅ 3. Joint details – bolts – welding
This is the “backbone” that connects the entire structural system. Just 1 wrongly drilled hole, 1 bolt with insufficient strength or 1 open weld is enough to cause the structure to be misaligned or not withstand the force as designed.
📌 Need to check:
- Bolt type (strength grade 8.8, 10.9…), quantity, diameter
- Weld position, weld thickness according to standards
- Have a weld test, tensile test if needed
💡 Suggestion: CMC Architects always integrates detailed connection drawings in each component - making it easy for the workshop to construct, easy to control and minimize errors.
✅ 4.Equipment – machinery – processing technology
Modern steel structures cannot be cut - assembled - welded in the traditional "manual" way. To ensure accuracy, the workshop must have a standard production line, using CNC, plasma machines, welding robots if necessary.
📌 Check:
- The machine has enough capacity to process the correct size
- The cutting surface is not pitted or burnt
- The weld is even, deep, and not porous
🎯 This reduces installation time on site and increases absolute accuracy.
✅ 5.Input and output quality control and monitoring process
Last but not least – quality control process before, during and after production.
📋 Must have:
- Checklist for each component
- Quality Control (QC) person with expertise
- Production diary - supporting images
- Acceptance report between the designer and the processing unit
👉 Chất lượng không thể kiểm bằng cảm tính – phải kiểm bằng quy trình, số liệu và chứng từ rõ ràng.
🧠 Summary: Do it right the first time – save money down the line
Steel structure production is not just “cutting – welding – assembling”. It is a closed technical process, requiring careful preparation, deep expertise and a clear inspection process.
Checking the 5 factors before production not only helps ensure the safety of the project, but also:
- Reduces errors
- Shortens installation time
- Enhances the reputation of the construction unit
- Helps investors feel secure and saves costs
