ROOF JOINT SYSTEM REVOLUTION

The Stramit Speed Deck Ultra® and Stramit FarLap®

system changes the way long run metal concealed fixed

roof decking is designed and fitted. The Stramit FarLap®

roof joint system makes easy work of roof installation

by connecting the steel decking sheets of any length

with a simple snap-in-place unit – eliminating the need

for conventional step joints, without compromising the

integrity of the roofing structure.

The Stramit FarLap® system provides a strong joint and

weather resistant seal between lapped sheets, meaning

the need for structural modifications is not required.

Reliable and easily installed, the lightweight Stramit

Farlap® units simply clip onto the ribs of the bottom sheet

above a supporting purlin; then, the top overlapping

sheet is pushed onto the FarLap system, providing a

structural connection. The system can be installed at

any support member along the roof run and allows for

uniform purlin height, so there’s no need for structural

alterations or additional purlin.

Manufactured from advanced, high technology materials

• Stramit FarLap® is durable, weather-resistant and won’t
  affect the durability performance of your Stramit roof or
  your roof warranty. With the joint connectors moulded
  from DuPont Zytel nylon – a strong material used for
  extreme environments, the sealing foam creates a strong
  lap joint as the nylon connectors hold both sheets

securely together while the foam seal takes the shape of

the sheet profile – making the joint waterproof.

The Stramit Farlap® units are available in either a 700mm

long system to match the cover width of Stramit Speed

Deck Ultra decking sheets, or seven metre pre-assembled

rolls to cover 10 sheets at a time. Thoroughly tested by

independent testing authorities and the Stramit Research

and Development laboratory for strength and weather

resistance, testing was also integral in investigating the

effect of sheet movement due to thermal expansion.

The Stramit FarLap® system allows long length roof

sheeting applications to be reduced to shorter more

easily handled sheeting lengths which allows for lower

transport costs, safer work practices, smaller cranes and

smaller crews. Plus, Builders can now lay extra long sheets

without the need for structural modifications or on-site

roll forming and there’s no need to involve fabricators or

designers in the process. This roofing system now offers

difficult site access jobs a completely new perspective.

Using shorter sheet lengths connected with the Stramit

FarLap® system can solve the trickiest site problems

And last, but certainly not least, the Stramit FarLap®

roof joint system is low-profile and flawlessly blends

in architecturally with the rest of the roof creating

continuous clean lines – making it the perfect steel

roofing project solution.

The National Construction Code 2016 Part 2 stipulates that gutter

systems when installed on residential buildings should be capable

of removing a given volume of water overflow. Numerous means of

achieving this objective are given in NCC Volume 2 Part 3.5.2, one

such measure is slots provided in the front face of the gutter.

Stramit® Trad-Line Gutter is a rollformed

rainwater product, designed for residential and

commercial applications. Trad-Line has a full

range of COLORBOND® steel colours to choose

from as well as matching accessories.

A key feature of Trad-Line is the slots on the

front face, which have an area of 1200mm^2 /m

and provide an overflow volume of 0.5L/s/m.

This overflow is adequate for most residential

construction projects.

The table opposite shows the maximum sloped

length of roof that can feed into the gutter for

the overflow through the slots to be sufficient.

The full Stramit® Rainwater products range

includes valley gutter, ridge capping, edge roll,

cappings, flashings and more.
