Polyester Coated
Box Profile V's Corrugated Profile
Box Profile and Corrugated sheets are the same price.
They are available in the same material options, just made on a different machine.
There are several different box profiles. This is the one we do:
Coating on sheets & flashings
PVC Coated
GreenCoat
Polyester coated
-
Cost-effective
-
Commonly used for farm buildings

Overlapping Sheets
Box Profile Overlap
- Side Lap:
This is where one sheet overlaps the next sheet along its length (across the width of the roof).
- Box profile sheets have one overlap rib (slightly narrower).
- There is one underlap rib (slightly wider with a flange to sit on the purlin)
- There is only a one rib overlap.
- Stitcher screws are used to secure the sheets together.
- On lower roof pitches, a lap tape may be added for extra weather protection.
- End Lap
This is required when the roof slope is longer than a single sheet length.
- One sheet overlaps the sheet below it vertically (from ridge down to eaves).
- Typical end lap:
- 150mm–200mm for steeper pitches
- 200mm–250mm+ for lower pitches
- Lap tape is recommended between laps.
Corrugated Overlap
- Side Overlap (Across the Roof)
This is where one sheet overlaps the next sheet horizontally.
- Standard practice is one full corrugation overlap.
- In more exposed or windy locations, one and a half corrugations may be recommended.
- The overlap should face away from the prevailing wind to reduce the risk of wind-driven rain.
- Use stitcher screws at regular centres along the lap (typically every second corrugation or as specified).
- For low pitches, apply lap tape along the overlap for additional weather protection.
- End Overlap (Down the Roof Slope)
Required when the roof length exceeds the sheet length.
Typical minimum end laps:
- 150mm – Roof pitch above 15°
- 200mm – Roof pitch between 10°–15°
- 250mm or more – Roof pitch below 10°
Additional guidance:
- Always place the upper sheet over the lower sheet so water sheds naturally.
- Use sealant tape between the laps, especially on lower pitches.
- Fix both sheets securely through the crest into the supporting purlin beneath.
