For the safety of public traffic, guardrails are installed on the Highways. They avoid an errant vehicle from hitting roadside obstructions which may be either man-made (sign structures, culvert inlets, utility poles) or natural (trees, rock croppings), running off the way and going down a steep embankment. They are a safety guard installed by the government. There is a number of Highway Guardrail Manufacturers India who makes them keeping in mind the quality standards.
Presence of Guardrails in Public places
A number of public places are fitted with guard rails as a way of shield against accidental falls. Any abrupt change in elevation where the higher portion is available makes a fall possible. Due to this responsibility and liability, rails are placed to guard people using the premises. Guardrails are generally necessary by code where there is a drop of 30" or more. Examples of this are both architectural and environmental. Environmental guardrails are located along hiking trails were the neighboring terrain is steep. Railings may also be located at scenic overlooks.
Guardrails in Buildings
Guardrails in buildings can be frequent and are mandatory by building codes in many circumstances. Guardrails along stairways are familiar and catwalks and balconies are also lined with them. An example of a common housing guardrail is a wood railing around a deck or patio. This is typically built on-site from pressure treated lumber, featuring a simplistic design of vertical baluster spaced every 3.5" to fulfill with the building code.
Construction options Available for Guardrails
Other guardrail construction options are available. Cable railings normally use stainless steel cables strung horizontally. Glass balusters and glass panels open vision while still providing safety, as at the Grand Canyon Skywalk. With the increasing status of composite lumber for adorning, manufacturers are providing composite railing components. Wrought iron is another choice that is customary and strong.
Building codes also want that no opening in a guard be of a size such that a 4" sphere may pass. There are three exceptions according to the 2003 International Building Code Section 1012.3 which allow openings to not exceed 8" or 21" depending on residence groups or special areas. Thus to conclude, guardrails are used in a number of spheres. For the highways, they are a must.
