Available Product Sizes
From compact window headers up to massive 6.0m garage door spans, we produce temporary steel lintel supports in 20cm increments to cover all common construction openings.
Applications Matrix
| Rapid Head Size (Metres) | Typical Structural Application |
|---|---|
| 0.4m – 1.5m | Small window, service conduits, and electrical openings |
| 1.8m – 3.0m | Standard residential window scopes and classic single doorways |
| 3.0m – 4.5m | Large structural doorways, wide double-windows, and archways |
| 5.0m – 6.0m | Double garage doors, wide commercial shopfronts, and major structural entryways |
Note: High-grade carbon steel allows our beams to easily handle high structural pressure without bend or micro-fissuring. Full engineering documentation is shared upon delivery.
Smart Sizing Estimator
We recommend adding a minimum of 50mm Seating Allowance (100mm total) to your opening width to sit the Rapid Head safely on masonry blocks. Enter your opening dimension below to estimate your exact size.
Custom Length Up to 10 Metre Spans
For commercial store fronts, dual-driveway garage openings, or industrial framing requirements that exceed 6 meters, we support builders with our engineered joining coupling system.
By securely joining two Rapid Heads using engineered interlocking sleeves, builders can span up to 10 meters safely. This gives your block-layers maximum flexibility without requiring massive permanent steel sections or dangerous unbraced spans on major projects.
