Each hole contains a specially formed t-nut to allow modular climbing holds to be screwed on to the wall. With manufactured steel or aluminum walls, an engineered industrial fastener is used to secure climbing holds. The face of the multiplex board climbing surface is covered with textured products including concrete and paint or polyurethane loaded with sand. In addition to the textured surface and hand holds, the wall may contain surface structures such as indentions (incuts) and protrusions (bulges), or take the form of an overhang, underhang or crack.
Some grips are formed to mimic the conditions of outdoor rock, including some that are oversized and can have other grips bolted onto them.
History

Gym climbing is becoming an increasingly popular urban sport and provides many people with the opportunity to try some aspects of the sport of rock climbing. Bouldering gyms focus on bouldering rather than roped climbing.
Wall Types
Some other types of walls include slabs of granite, concrete sprayed on to a wire mesh, pre-made fiberglass panels, large trees, manufactured steel and aluminum panels, and textured fiberglass walls.
Routes and grading
Holds come in different colours, those of the same colour often being used to denote a route, allowing routes of different difficulty levels to be overlaid on one another. Coloured tape placed under climbing holds is another way that is often used to mark different climbing routes. In attempting a given route, a climber is only allowed to use grips of the designated colour as handholds but is usually allowed to use both handholds and footholds of the designated colour and surface structures and textures of the "rockface" as footholds.
The grade (difficulty) of the route is usually a consensus decision between the setter of the route and the first few people who climb the route.
Many indoor climbing walls have people who are assigned to set these different climbing routes. These people are called route setters or course setters.
As indoor climbing walls are often used to check the development of climber's ability, climbs are color coded.
