7 Ways to Save Money on Your Steel Building
7 Ways to Save Money on Your Steel Building
The most cost-effective design for a pre-engineered metal building (PEMB) depends on several factors, including the building’s size, intended use, and local building codes.
However, some general guidelines help keep costs low while maintaining structural integrity:
1. Simple Rectangular Shape
- A clear-span design (no interior columns) is more cost-effective for small to medium buildings, while multi-span (with interior columns) is better for wider structures.
- Avoid complex layouts with multiple corners, wings, or irregular shapes. A basic 40×60 or 50×100 rectangular footprint is the most efficient.
2. Standard Roof Pitch
- A 1:12 to 4:12 roof pitch is ideal. Lower slopes reduce steel usage, while higher pitches increase costs due to extra framing and materials.
3. Standardized Bay Spacing
- 25’ to 30’ bay spacing is optimal for balancing steel efficiency and cost. Closer bays increase steel usage, while wider bays may require heavier frames.
4. Minimal Customizations
- Standard gable roofs are more affordable than complex rooflines (hip, mansard, or multi-level).
- Limit the number of doors, windows, and framed openings to reduce framing costs.
- Use standard insulation packages instead of custom solutions.
5. Economical Wall & Roof Panels
- 26-gauge PBR (Purlin Bearing Rib) panels are cost-effective and durable.
- Choose galvalume roofing for long-term savings over painted panels.
- Single-skin panels with standard insulation are cheaper than insulated metal panels (IMPs).
6. Foundation Considerations
- A simple slab-on-grade foundation is the most cost-efficient. Avoid deep footings unless required for local soil conditions or heavy loads.
7. Optimize Steel Tonnage
- Work with a PEMB manufacturer that value-engineers the design to minimize steel weight without sacrificing strength.
- Limit mezzanines and heavy loads unless necessary.
