Aluminum Multi-Line & Pipe Railing Systems

The Multi-Line Guardrail (Horizontal-Line Rail) system is an alternative concept which is popular with "high-tech" designs. The ATR Technologies’ Multi-Line Guardrail offers architecturally pleasing designs that compliment the traditional "Pipe Rail" systems.

Our Multi-Line rail system utilizes a variety of interchangeable parts to allow the creation of many different designs. ATR Technologies’ system allows round or oval components to be combined with square or rectangular shapes to create a variety of different architectural designs. New extrusion dies can be developed as required in order to meet new architectural designs.

For areas accessible by the public, current building codes set the design criteria to include 4 in. maximum openings below the top rail. On the other hand, areas accessible for industrial use permit the spaces below the top rail to be increased up to 12 in. maximum openings. Among other things, the horizontal components must be spaced properly such that a sphere of the maximum opening diameter can not pass through the multi-line panel area. ATR's standard design for this railing system includes equally spaced midrails below the top rail that maintain the maximum opening criteria. Midrails tend to be substantial in order to prevent excessive deflection, especially when actual use is considered.

Post spacing is determined by the load criteria, post size, railing height and desired post spacing. In most cases, posts are located 48 in. to 60 in. on center. ATR's standard post spacing method divides any given railing section into equal spaces within the maximum post spacing criteria.

The ATR Technologies’ traditional "Pipe rail" allows for flexible designs, in-line, flush, machined fittings and bent transitions. Typical aluminum pipe rail is manufactured with 1-1/2 in. Sch. 40 aluminum pipe. This system is used for many industrial applications and is featured in many ornamental applications, often with bright paint colors.
