As the winter season approaches, construction projects face unique challenges, especially when it comes to steel structure installation. HIG Modular, a leader in modular and steel structure solutions, is committed to maintaining high safety standards and quality performance during winter construction. The company follows a strict set of procedures to ensure that steel structure projects are completed efficiently and safely despite low temperatures.
1. Adherence to Winter Construction Guidelines
Steel structure fabrication and installation during winter require careful attention to established regulations specific to cold weather work. HIG Modular ensures that all procedures align with national winter construction standards to guarantee safe and effective execution.
2. Temperature Adjustments for Component Shrinkage
When steel components are fabricated in positive temperatures but installed in negative temperatures, thermal differences can cause structural shrinkage. HIG Modular carefully considers these temperature variations and adjusts for potential deviations during installation, ensuring precise fit and secure assembly.
3. Specialized Training for Welders
In cold weather conditions, welding becomes more challenging due to material brittleness. HIG Modular prioritizes the training of welders, ensuring they are certified in cold-weather welding procedures and possess the necessary qualifications to carry out work at lower temperatures safely.
4. Compliance with Material Quality Standards
Steel materials and connection components used in cold weather construction are required to meet stringent quality standards. All materials used during winter construction come with quality certifications, ensuring that performance aligns with design and product specifications, even in challenging conditions.
5. Strict Welding Rod and Flux Handling
Proper handling and storage of welding rods and flux are critical for quality welds in low temperatures. HIG Modular enforces a policy where welding rods are not exposed for more than two hours, ensuring they are reheated if necessary. This prevents moisture absorption, which can negatively affect welding performance.
6. Quality Control for High-Strength Bolts
For high-strength bolts used in winter construction, HIG Modular ensures that all bolts are accompanied by product certificates and undergo torque and axial force verification tests at low temperatures to confirm their integrity and reliability.
7. No Water-Based Paint for Steel Coating
Water-based paints are not suitable for cold weather as they can affect the quality of the coating. HIG Modular ensures that all paints used for steel structure coatings during winter are compliant with the requirements for cold-weather performance, preventing issues like poor adhesion or curing.
8. Precise Shrinkage Adjustments During Component Fabrication
Steel components are fabricated with allowance for shrinkage, considering both welding shrinkage and compression deformation. HIG Modular ensures these allowances are precisely calculated, especially in negative temperatures, to prevent any misalignment during assembly.
9. Optimized Assembly Process
During the assembly of steel structures in cold weather, HIG Modular follows a carefully defined process. Starting from the interior, each layer of components is assembled progressively outward. Before assembling in freezing conditions, the company performs tests to determine the necessary welding shrinkage allowance.
By following these meticulous steps, HIG Modular ensures that steel structure projects are not only completed on time but also meet the highest safety and quality standards. As cold weather presents additional challenges, the company remains dedicated to maintaining excellence in every stage of construction, providing clients with durable, reliable, and safe steel structures year-round.
