We undertake sign board works for various road projects. Recently we have started fully equipped fabrication shop at our MIDC Mahad facility. Our advantage over others is our designing team, who are experts in designing steel structures for gantry, cantilevers etc. with suitable RCC foundations. We use various grades of Avery Dennison or 3M reflective sheeting as per the client’s requirement.
Various Signs are cut on most advance cutter plotter in our sign shop and every care is taken while pasting to ensure its durability. . The reflective sheet manufacturers are extending us excellent technical support as and when required. All these factors are helpful in fulfilling client’s requirements in scheduled time.
The color, configuration, size and location of all traffic signs for highways other than expressways is to be in accordance with the code of practice for Road Signs; IRC: 67 or as shown on the drawings.
For Expressways, the size of the signs, letters and their placement shall be as specified in the Contract drawings and relevant specifications.
GANTRY / CANTILEVER :
We are expert in fabrication and erection of Over head Gantry & Cantilever. We have own fabrication unit and we are liable to fulfill client’s requirements. We have completed many projects for NHAI, STATE HIGHWAY, PWD, CPWD MMRDA, MSRDC etc. across India.
ROAD SIGNAGE :
1. Mandatory / Regulatory Signs: These signs are used to inform road users of certain rules and regulations to improve safety and free flow of traffic.
2. Cautionary / Warning Signs: These signs are used to caution the road users of the existence of certain hazardous conditions either on or adjacent to the roadway, so that the motorists can become cautious and take the desired action.
3. Informatory Signs: These signs are used to provide information and to guide road users along routes. The information could include names of places, sites, direction to the destinations, and distance to places to make the travelling / driving easier, safer and pleasant.
MATERIAL FOR SIGNS :
The various materials and fabrication of traffic signs used by us are as follows;
Alluminium: Alluminium sheets used for sign boards shall be of smmoth, hard and corrosion resistant alluminium alloy confirming to IS:736 – Material Designation 24345 or 1900 or as per drawing.
Generally these retro-reflective sheeting are known as:
(I) High Intensity Grade Sheeting: This sheeting is encapsulated lense type consisting of spherical glass lens, elements adhered to a synthetic resin and encapsulated by a flexible, transparent waterproof plastic has a smooth surface.
(II) Engineering Grade Sheeting: This sheeting is enclosed lens type consisting of microscopic lens elements embedded beneath the surface of a smooth, flexible, transparent, water-proof plastic, resulting in a non-exposed lens optical reflecting system.
The alluminium sheeting is to be de-greased either by acid or hot alkaline etchingand all scale/dust removed to obtain a smooth plain surface before the application of retro-reflective sheeting. If the surface is rough, approved surface primer may be used. Complete sheets of the material to be used on the signs except where it is unavoidable.
- Message/Borders :
The message (legends, letters, numerals, etc.) and boarders is either screen-printed or cut-outs.
BACK FRAME FOR SIGNS :
The size of angle depends on size of boards. We use 35 x 35 x 5 mm angle for less than 0.9 Sqm, 40 x 40 x 5 mm angle for more than 0.9 Sqm but less than 2.0 Sqm. and 50 x 50 x 5 mm angle for more than 2.0 Sqm of boards or as per drawing.
POSTS AND MOUNTING FOR SIGNS :
In case of signs supported on two or more posts if necessary bracing may also be provided. Normally, signs with an area upto 0.9 sq.m. is mounted on a single post (50NB medium class pipe), and for greater area two or more supports is provided. It depends on size of boards. We use the pipe (50 NB to 100 NB Medium class) for vertical post or as per drawing.
All components of signs and supports, other than the reflective portion of G.I. posts are thoroughly desealed, cleaned, primed and painted with two coats of epoxy paint. Any part of mild steel post below ground shall be painted with three coats of red lead paint.
The signs is fixed to the posts by welding in the case of steel posts and by bolts and washers of suitable size in the case of reinforced concrete or G.I. posts. After the nuts have been tightened, the tails of the bolts shall be furred over with a hammer to prevent removal.
