Johannesburg architects

Q: Why do you specialize in Lightweight Steel Framing (LSF) over traditional methods?

• A: We focus on LSF because it offers superior benefits: dimensional stability, non-combustibility, resistance to pests (termites), and unmatched strength-to-weight ratio. This allows us to achieve structural designs that are often impossible or cost-prohibitive with timber or concrete.

Q: How does LSF affect the design and architectural phase?

• A: LSF allows for greater design flexibility and longer spans without internal support walls, enabling open-plan layouts. Our LSF contractors work with your architects from day one to optimize the plans for maximum efficiency, precision, and material savings.

Q: Are your LSF frames prefabricated or cut on-site?

• A: Our process utilizes advanced prefabrication. The LSF components are precisely manufactured off-site using computer-aided design (CAD). This guarantees dimensional accuracy, minimizes on-site cutting and waste, and accelerates the erection process significantly.
  
  Building on Existing Structures

Q: Why is LSF better for adding floors on top of an existing building?

• A: The main advantage is weight. LSF is substantially lighter than traditional concrete or masonry. This is critical because it minimizes the required strengthening of the existing foundations and lower structural elements, making vertical extensions safer, faster, and often more affordable.

Q: What is the process for assessing an existing building for an LSF vertical extension?

• A: It begins with a comprehensive structural assessment by our engineers. We analyze the existing foundations and load-bearing walls to determine the maximum load capacity. We then design the lightweight LSF structure to stay within those limits, ensuring structural integrity and code compliance.

• Durability & Sustainability

Q: Does LSF rust or degrade over time?

• A: No. The steel used in LSF is protected by a high-quality galvanized coating (zinc alloy), which provides excellent corrosion resistance. When properly installed within the wall system, LSF structures are exceptionally durable and designed to last for the lifetime of the building.

Q: Is LSF an environmentally friendly building solution?

• A: Yes. Steel is a highly recyclable material, making LSF a sustainable choice. Furthermore, the framing's precise nature allows for superior insulation detailing, leading to better energy efficiency and lower long-term heating and cooling costs for the building occupants.
