Roof safety aluminium railing system

The barrial safety railing system is a permanent system for protection against falling from height, which meets all the technical and statutory constraints in connection with accessible flat roofs (norms NF EN ISO 14122-3, NF E 85-015 and NF EN 13374 class A)

Compatible with the net attachment system Accrofil.

Making inaccessible flat roofs safe with these railings is a legal obligation.

A tested and approved system. Thousands of references in France and abroad.

Assets of Barrial

• Delivered custom-made with layout plan
• Mandatory solution for new construction and high-priority for renovation
• In accordance with DTU 43.1 and 20.12

A modular and adaptive system for each different case

This system allows a unique solution for each case which is really easy to install on-site.

All the different models of guardrail (straight, right-angled, curved, folding) are part of the same system.
The combination of the differents fixing modes (inside parapet wall, top of parapet wall, façada, roof slab, steel decking) allows the adaptation for more complexed construction site.
The finish (untreated aluminium or lacquered RAL Danilac) of Barrial can be adapted to the aesthetics of your building.

Straight stationary post

The stationary straight post is suitable for most cases. Z shoes support 60 x 22 mm posts, other shoes (A60, BA, D, M) 45 x 22 mm posts.

Curved or angled stationary post

Curving (radius 1000) or angling ( 15 °, 30 °, 45 °, other possibilities on request) enhance the discretion and the aesthetic of the guardrails on your building.
It keeps the user away from the edge of the flat roof.
If the edge of the roof is on the constructible limit, curved or angled models are more suitable in constructible size.

Pre-assembly and pre-adjustment in factory

The number and the spacing of clamps for rails are designed by our assessment department depending on the measurement of the parapet wall and on the type of shoe. Posts are customed made. Clamps and caps are installed in our factory.

Folding post

When aesthetic or environmental obligations do not allow visble stationary guardrails, this model is a compromise between architectural requirement and safety necessity.

Rails and accessories

Handrails (45 mm or 35 mm depending on configurations) and rails (Ø 35 mm) are discreet and geared towards the terrace's interior.
The standard length is 3000 mm.

Handrails and rails are joined together with the junction piece, ensuring a safe and aesthetic continuity between the components.

Oncorners, rails are linked by angle pieces with variable degree in order to suit every configuration.

Wall fixing pieces and end plugs ensure the finish on ends.

The clamp was designed to simplify the installation of the Barrial system and to allow an easy adjustment of the rail's height after installation if required.

An easier installation

The use of clamps ensures easy installation of the rails.
The use of the dani alu wrench (hex wrench n°4) guarantees a quick and safe clamping.

A facilitated adjustment

The fixing screw stays accessible after installatio to allow the height of the rail to be altered without having to uninstall them. 

Accrofil^®

Safety net attachment system for roofers installing Barrial railings

Accrofil is a safety net attachment system for roofers, designed specifically for Barrial permanent safety railings.
With the addition of Accrofil, Barrial railings now meet a dual requirement :

• the permanent safety of inaccessible flat roofs or roof-top plant rooms.
• compliance with the requirements of the new standard for the safety of roofers (NF P 93-355)

Using accrofil attachments, the net acts as a temporary infill to the gaps between the rails of the railing whilst works are being carried out, both preventing items from falling and improving personal safety on the roof.

Accrofil is recommended for use where Barrial is fixed to a parapet wall, with straight, angled, or curved posts.

Barrial^® gate

The Barrial gate is custom made for a perfect integration on Barrial systems, including those with curved or angled posts. 
The width of the way is 800 mm for the standard version, but can also go from 500 to 1000 mm on request.
The gate must be installed so that it opens towards the terrace's interior.

One result of the changes to the thermal regulations is the increasing trend to insulate parapet walls.
Zd and Zc shoes are adapted for the installation of guardrails on insulated parapet walls. A EWIS Couvernet coping with plates or thermal break console (th) has to be put on top of them.

Compatible with stationary post :

• straight
• curved
• angled 15°/30°

Zd shoe

The Z shoe's extension allows movement within the shoe  to move the shoe inside the parapet wall made of a spoiler or inside the insulation up to 200 mm.
The piece allowing this move is predimension in factory in accordance with the parapet wall specifications (height of the spoiler or width of the insulator).

Zc shoe

The fixing console for insulated parapet wall can be adapted to the Z shoe with stationary post.
It allows to compensate insulations with width from 60 to 150 mm. The height and the offset are pre-adjusted in factory, in accordance with the specifications of the insulation given.
The system also has a connection plate for the waterproofing.

Z shoes are completed with a EWIS Couvernet type aluminium coping, with plate or thermal break console (th).

Amplitude of use

The Barrial safety guardrails is a permanent and collective protection system agains falls from heights of flat roofs. It is in accordance with regulatory constraints (norms NF EN ISO 14122-3, NF E 85-015 and NF EN 13374 A class)

Compatible with Accrofil system.
