The Scaffolding Journal – The History of Scaffolds

The Scaffolding Journal – The History of Scaffolds

Scaffolds have been in use since time immemorial. The earliest recorded use being in the construction of the ancient structures in ‘The Land of Civilization’, Egypt.

wood scaffolding

Scaffolding is one of the most vital components of construction projects, as well as various other industrial and commercial operations. Although its purpose of application remains the same, the types of scaffolds used have evolved over time. The major change in what scaffolding used to be and what scaffolding is today is in the materials used. The main reason for this change in material from traditional bamboo and wood scaffolds to modern steel and alloy scaffolds is safety.

scaffolding in Egypt

Egypt is home to marvelous huge ancient structures that are so remarkable that they are said to be built by aliens ages ago. In truth, however, Ancient Egypt and other ancient civilizations had knowledge of engineering and construction practices that were far ahead of their time. The Pyramids and statues of Ancient Egypt we constructed by slaves / laborers under the rule of the Pharaohs. They used wooden scaffolding to lift huge stones and place them at the right places, guided by highly-skilled engineers. These wood scaffolds were also used as a base for workers to carve detailed statues out of colossal rocks or blocks of stone, from the top to the bottom.

Scaffolding in India

Moving to the far East, to countries like China and India, not as far back in time as Ancient Egypt, Bamboo and wood poles have been used in construction. The use of bamboo and wood poles to form scaffoldings dates back decades, maybe even centuries ago, and is still prevalent in some parts of the East. Bamboo is extremely flexible, strong and durable, capable of bearing heavy weights when bound properly. The use of bamboo scaffolds in construction proved to be ideal due to its high resistance and strength. The bamboo or wood poles were bound together using ropes to prevent them from slipping and sliding and to form a strong, stable structure. Although, in time as steel was adopted in most countries and by most construction companies, many still use bamboo and wood to construct scaffoldings today.

modern scaffolding

Advancing forward, scaffolds have never been more different, safe or secure as they are today. Modern scaffolding or the base of what scaffolding is today was first introduced in the early 20th century. These scaffolding were metal fixings like clamps and mounts were introduced to replace ropes to hold scaffolds together. As time went by, and there was rapid development in every field, through the innovation and development brought about by the industrial age, there was a transformation in the construction sector. The requirements of scaffolding were diversified and increased to cater to the construction of tall buildings and skyscrapers. To satisfy these requirements metal, steel and alloy scaffoldings were engineered and manufactured.

Today, scaffolding can be classified into various types that service specific and standard purposes. The types of scaffolding used in the Construction Industry today include:

  • Single,
  • Double,
  • Cantilever,
  • Suspended,
  • Patented,
  • Trestle, and
  • Steel Scaffolding.

Things To Know When Talking About Steel Gratings

Things To Know When Talking About Steel Gratings

Many of us know what gratings are, and what their applications are in homes and various industrial settings. However, the majority of the people do not know much about gratings or are not that well versed in the right terminology in defining, differentiating or identifying variations in gratings and its several types. This post is to help you know more about gratings, terms used in specifying or identifying its various types and specifications, and other terms that might prove helpful at some point in time.

Gratings, in general, can be defined as a framework or a grid of crossed or parallel bars, normally preventing access through an opening, while permitting communication and ventilation. This definition of gratings or grates is broad, not restricting its applications by definition. “Entry prevention” entails its applications as a structural surface, such as a wall, floor, fencing, pathway, roof, and such. Specific to gratings, these structural surfaces are nothing but a well-engineered framework, with variations in design that provide effective ventilation between compartments, with no compromise in functionality or structural capability. Although Gratings are manufactured with numerous variations, at Oasis Metal Manufacturing LLC we produce standard and shaped steel gratings, stair treads, and fixing clips.

Terms Associated with Steel Gratings

Some common terms or terminology used in reference to the specifications, types and other variations of steel gratings are:

Grating

A steel grid formed using load-bearing bars and crossed bars through resistance welding.

Span (Length of the Grating)

The span or length of the grating is measured along the direction of the load-bearing bars. Variations in the span of the gratings usually cause a difference in its load-bearing capacity.

Width of the grating

The width of the grating is the measure of distance along the direction of the cross-bars.

Plain load-bearing bar

Plain load-bearing bars are normal flat load-bearing bars, which are used to produce plain or flat surface steel gratings.

standard steel gratings

Serrated load-bearing bar

Serrated load bearing bars are flat on one side and serrated or ridged on the other. The seated edge provides the surface of serrated steel gratings, which are commonly used for their anti-slip properties as industrial flooring.

Pitch

The pitch is the center-to-center distance between two load-bearing bars or two cross bars.

Binding bar

Binding bars are flat bars used to construct a border for the framework. These flat bars are welded to shaped panels at each end and at cut-outs to form panels or tiles.

Grating Gross Area

The Gross Area of a Grating is the total area of the grating including the cut out areas. The gross area is not the net or actual area of the grating as areas that are cut out or removed are also calculated.

Grating Net Area

The Net area of a Grating is the actual area of the grating. It refers to the total or gross area, excluding (minus) the area cut out.

Cut-out

Any area of a grating that is required to be shaped and removed or cut out to allow pipes and columns to pass through is called a cut-out. A Cut-out can with be Straight Shaped- cut-out with straight edges or straight lines, or Curved Shaped – cut-out with curved lines or edges.

Toe Plate

Toe plates are large-sized flat bars which are welded to the edge of the steel gratings or grating panels, for safety and precautionary purposes.

Curb Angles

Curb angles are support fixtures that are installed onto concrete or a steel frame to support grating panels.

Erection Clearance

Erection Clearance is a permitted distance from a grating panel to an adjacent panel or structure.

Stair Tread

Stair Treads are steel gratings or panels with end plates and non-slip nosing, which are used in stairways. End plates are plates that are welded to each end of a stair tread, allowing easy installation to steelwork or a steel frame. Non-slip nosing is a special anti-slip bar, that is welded to grating panels or stair treads to provide a grippy surface and prevent slipping.

With knowledge of these basic terms, you can easily understand variations in the different types of steel gratings, custom panel designs and cut-outs, and differences in weight-bearing capacities of gratings. This can further help you choose the right type of steel gratings, which are ideal for the types of application and use.
