From workshop to site, a single contact
ADL manufactures in its Bouskoura workshop and installs on site with its own teams: barriers, railings, catenary protection, steel bridges and footbridges.
Installation is coordinated with the contractor and the project manager, in line with the site schedule and safety instructions.

The reference framework for road equipment
In Morocco, road equipment falls under the Moroccan standards (NM) of the 10.9 series, drawn up within the IMANOR standardisation committee “Road signs and road equipment” (committee 059). Several of these standards adopt French or European standards, for example:
- NM 10.9.338, which adopts NF P 98-426;
- NM 10.9.270, which adopts EN 1317-3.
Useful references for our products:
- BN4 barrier: Moroccan reference NM 10.9.299, which adopts the French standard NF P 98-421;
- Bridge railings: NF P 98-405 standard;
- Road restraint systems: the European EN 1317 series, which notably defines performance tests.
The requirements that apply to a project are those of its specifications; our engineering office checks them before manufacturing. These references are given for information only; they are not ADL certifications.
An approval by a project owner or an infrastructure manager is only mentioned on a product sheet when ADL holds the corresponding document, which can then be provided on request.
A division dedicated to road structures
ADL Infra is the Afrique Découpe Laser division dedicated to steel equipment for road infrastructure. It relies on the resources of our workshop — sheet laser cutting and tube laser cutting, bending, rolling, welding and assembly — and on our engineering office, which checks the drawings and prepares manufacturing.
For contractors and project owners
We work from the structure's drawings, bill of quantities and specifications. Our engineering office produces the shop drawings from the project drawings, and our sales team sends you a detailed quote, including for a consultation or a public tender.
From manufacturing to installation
Components are manufactured in our Bouskoura workshop, then installed on site by our teams, in coordination with the contractor and the project manager. For a first discussion, a quote request with the drawings and the bill of quantities is enough.
Frequently asked questions
What is a BN4 barrier?
It is a steel safety barrier for bridge edges: horizontal rails are fixed to supports anchored into the structure with shear bolts. ADL manufactures the supports in its Bouskoura workshop; the rails are galvanised sections imported by ADL. The BN4 type is described by the Moroccan reference NM 10.9.299, which adopts the French standard NF P 98-421.
Is the S7 railing a safety barrier?
No. The S7 is a railing that protects pedestrians on bridge footways; it does not restrain vehicles. It can complement a safety barrier on the same structure.
Do your products have an approval?
An approval is specific to a product and often to a project or a project owner. We only mention it on a product sheet when we hold the corresponding document, which can then be provided on request. For a tender, ask us for the file available for the equipment concerned.
Do you install on site?
Yes. ADL manufactures the equipment in its Bouskoura workshop and installs it on site with its own teams. In your request, state the structure, the length to be fitted and any site access constraints.
A structure to equip? Send us the drawings and bill of quantities.
Tell us the structure, the length to be fitted, the type of system and the target date. Our engineering office will get back to you with a study and a quote.
