The SR1 series consists of a cylindrical main structure of carbon steel, with a standard height of 4.4 metres. Alternatively, the unit incorporates a lower compartment in the access door to house the power supply, thereby facilitating maintenance activities. The SR1 series comes in a vertical or horizontal (Post – Top) layout; an adaptation bracket is required for the Round and Square series, this enabling the luminaire to be tilted at an angle of 5º.

The mechanical strength of this element and the durable materials used make the SR1 series highly resistant to aggressive environments and vandalism. The S-235/275-JR carbon steel used, together with the process of galvanizing by dipping and subsequent application of a two-component polyurethane finish confer excellent technological properties on the column in terms of resistance and durability.
