Plastic HDPE and galvanised steel safety road barriers for road work zones, site perimeters, and traffic management — available at Multi Trade Combines, Guwahati.
Safety road barriers are portable or fixed physical delineation devices placed on roads and in work zones to guide traffic, protect workers, and prevent vehicles from entering hazardous areas. Plastic (HDPE) road barriers are hollow, lightweight units that interlock end-to-end to form a continuous barrier line; they can be ballasted with water or sand when higher stability is required. GI (galvanised iron) barriers are heavier, welded steel units used for semi-permanent lane separation, pedestrian path delineation, and robust site perimeters where vehicle contact is expected.
Multi Trade Combines supplies plastic and GI safety road barriers from our Guwahati counter. Northeast India's ongoing road expansion — NHIDCL and NHAI projects on the Trans-Arunachal Highway, the Meghalaya highway improvement programme, and Assam's urban road upgrades in Guwahati — generates consistent demand for work zone safety products. Contractors must comply with MoRTH safety guidelines that mandate road barriers and signage at all highway work zones, and municipal work in Guwahati requires TMP (Traffic Management Plan) compliance with barriers and lighting.
Civil contractors and subcontractors working on road widening, bridge construction, utility trenching, and pavement rehabilitation on national highways and urban roads across Assam and the Northeast are the primary buyers. A road contractor must maintain road barriers throughout the active construction period, replacing damaged units regularly. Contractors working on multi-year NHIDCL projects in Arunachal Pradesh, Nagaland, and Manipur often purchase large quantities of barriers for long-duration projects.
Municipal corporations and public works departments use GI barriers for permanent pedestrian dividers on urban arterials, bus stop protection fences, and road medians in Guwahati and the seven sister state capitals. Police traffic management units use plastic road barriers for event management during festivals, VVIP movements, and emergency road closures.
Road barriers pair with safety cones for taper marking, caution/danger tape for fine-line delineation, and reflective tape applied to barrier faces for night-time visibility. The complete workzone safety package is available from our Safety Equipment range at Multi Trade Combines.

Plastic road barriers are made from high-density polyethylene (HDPE) or similar materials. They are lightweight, easy to move without machinery, and can be filled with water or sand to increase stability. They are suitable for temporary traffic management zones — construction site boundaries, road maintenance cordons, event management, and lane separation in urban areas. They resist corrosion and require minimal maintenance. GI (galvanised iron) road barriers are heavier, more robust, and provide greater resistance to vehicle impact — they are used as permanent or semi-permanent pedestrian and traffic separation fencing on urban roads, highways, and industrial facilities. Both types can be fitted with retroreflective tape for night visibility.
For temporary lane closure on a national or state highway, MoRTH guidelines and road contractor safety protocols typically require barriers spaced no more than 1 metre apart along the taper leading into the closure and at 2 metre spacing along the work zone boundary, plus advance warning signs from 500 m before the closure. A 50-metre work zone closure with a 30-metre taper would need approximately 65–80 barriers in total.
