Difference Between Modular & Tubular Scaffolding



Tubular scaffolding takes time and effort to set up, but it’s very versatile. You can connect the horizontal tubes to the vertical ones at almost any point, as long as you follow safety rules. Right-angle clamps hold the horizontal tubes to the vertical ones, and swivel clamps attach the diagonal tubes, making the system very durable.

Even though it’s not as popular as it used to be, tubular scaffolding is still commonly used in refineries, petrochemical plants, and power plants. It’s a flexible system that can fit almost any complex structure. While it does require more time and energy to set up, it provides the sturdy platform that many projects need.

Tubular scaffolding is perfect for projects that need to support heavy loads.

What is Tubular Scaffolding?

Scaffolding made of tubes is great for building jobs. It’s tough and useful in many ways. It is made of steel tubes that are joined together with couplers to make a strong structure that workers can use.

Tubular scaffolding, also called traditional scaffolding, tube and clamp scaffolding, tube and fitting scaffolding, or tube and coupler scaffolding, is made by connecting tubes with clamps and couplers. 

You can trust that tubular supports will last a long time. The steel tubes are strong and can handle heavy loads and bad weather. Tube-shaped scaffolding is cost-effective because it can be used again and again for many jobs.

Components of Tubular Scaffolding

Tubular scaffolding is very simple to set up because it only uses four basic components:

Standards (Vertical Tubes): These are the main support tubes that run from the ground to the top.

Ledgers (Horizontal Tubes): These horizontal tubes connect the standards, providing side support and keeping the scaffolding level.

Base Plates: These plates are placed under the standards to distribute the weight and ensure stability.

Bracing: Angled tubes that prevent the structure from shifting or collapsing, making the scaffolding safer for workers.

Couplers: Fittings that connect the tubes together.

Platform: A work surface made of metal or wood, supported by transoms.

Tubular support is great because it can be used in a lot of different ways. That’s because you can change its height and form to fit your project. Tubular scaffolding is a reliable choice that can be changed to fit any job, whether you are working on a house or a big office building.

This flexibility helps construction work go smoothly and efficiently.

Difference Between Tubular & Modular Scaffolding

Modular Scaffolds

  • It’s a modern type of scaffolding.
  • It’s assembled using prefabricated accessories.
  • It uses the tube coupling method, making it easier to assemble.

Tubular Scaffolding

  • This kind of structure is common these days.
  • The frame is put together with tubes.
  • Setting up takes time.
  • Construction teams can spend more time working on the job and less time setting up when they use tubular scaffolding. This makes them more productive overall.
  • Couplers and clamps connect tubular scaffolding. Fixed joining points connect modular scaffolding, making modular scaffolding safer. In places like Israel, using modular scaffolding is required.

When choosing scaffolding, consider the job length and your budget. But safety is the most important factor.

How Do I Select the Right Caster Wheel for My Scaffolding?

Right Caster Wheel for My Scaffolding

Scaffolding is a temporary structure that is supported by its scaffolding equipment. The equipment may be a base plate or a caster wheel, but it should be robust enough to bear the weight of the entire scaffolding and the scaffold users. That’s why picking the right set of scaffolding caster wheels is of utmost importance. 

The scaffold caster not only gives the 3D structure a base but also lets the scaffold move around. The wheels can be locked, and the erected scaffold can be used. The casters are inserted into the static scaffold tube to simultaneously make it mobile and secure. This will facilitate a variety of construction projects in the vertical plane and on uneven surfaces. The worker will be able to relocate the scaffolding without difficulty.

This blog will elaborate more on how to choose a caster wheel and its benefits.

What are caster wheels?

A caster (or caster) is an unpowered wheel designed to be attached to the underside of a larger object (the “vehicle”) in order to facilitate its movement. In numerous industrial applications, such as platform trucks, carts, assemblies, scaffolding, and tow lines in plants, high-capacity, heavy-duty casters are utilized.

In scaffolding, the caster wheels are attached to the bottom of the scaffolding to help it move around the worksite. 

What are the selection criteria for scaffold casters?

1. Select the appropriate size caster

The larger the diameter of the caster, the more labor-efficient and resistant it is to obstacles.

2. Select an appropriate material

Casters are categorized as super synthetic rubber casters, polyurethane casters, plastic casters, nylon casters, steel casters, high-temperature casters, rubber casters, etc. Casters made of various materials are used in various ground conditions and temperatures, and they must be selected based on the application. 

3. Determine the load-bearing mass

For identical-diameter mobile scaffolding casters with varying load-bearing requirements, the manufacturer typically produces multiple models, primarily to produce wheels and brackets with varying thicknesses or materials. When the terrain is relatively flat, the single caster load equals the number of casters installed on the equipment divided by 1.2 (the insurance factor).

4. Choose the bracket

The two types of brackets are orientation and universal direction. Typically, the material is carbon steel. In addition to stainless steel, you can get various types of plating, such as spraying, galvanizing, copper plating, nickel plating, etc.

5. Determine the method of installation

Typically, you can use a screw rod, plunger, expansion rubber sleeve, etc. for a moderate to light load. Use the bottom plate or have the caster directly welded to the equipment for heavy loads.

6. Breaking and locking mechanism

Functionally, brakes are typically divided into brake wheels and universal brake brackets. There are also friction brakes, positive brakes, side brakes, etc. Caster brakes must be effective. When workers are on scaffolding, they must stay put. Workers could fall if it keeps rolling, swiveling, or moving.

Most scaffolding casters have an easy-to-access braking mechanism that anyone can kick into place to prevent movement while working. Scaffolding needs a locking mechanism, too. Once the scaffolding is up, make sure it doesn’t move by itself. A locking mechanism is needed to keep scaffolding in place while workers do tedious work above it.

What are the benefits of a scaffold caster?

1. Mobility

Scaffolds with casters are ideal for moving. All tradesmen and industrial maintenance workers can do their jobs quickly and easily without needing a large scaffold or manual conversions. So, scaffolds can be moved and secured flexibly in different areas.

2. Safety

Regarding securing casters on scaffolding, safety is of the utmost importance. Because they promote motion, wheels and casters reduce physical strains and demands on employees when moving large loads. With the addition of a braking mechanism, the safety features are enhanced.

3. Scaffold caster wheel capacity

Casters have the advantage of being able to support the considerable weight without breaking. As a result of the caster wheel‘s rotation around an axle and bearing race, it is subjected to significantly less direct pressure than a conventional wheel. Because the wheel turns instead of the chassis, its load-bearing capacity is significantly greater than that of a conventional wheel.

Scaffold caster safety measures

Scaffoldings are prone to accidents and mishaps if proper caster safety precautions are not observed. Follow these guidelines to avoid unwelcome occurrences:

  • Avoid overloading the scaffolding. The casters will have to bear the additional weight, and they will buckle if the weight exceeds their capacity.
  • Do not drop heavy loads on casters, as the initial impact can cause them to degrade and may also cause structural damage.
  • Do not roll the scaffolding at a high rate of speed, as it can injure people and cause damage to any obstacles in its path.
  • Always lock the scaffold caster wheel in place when it is not necessary for the scaffolding to move. If it begins to move without your permission, accidents may occur.
  • Ensure that you immediately tighten any loose components of the casters.

Wrapping Up

A caster is a non-powered wheel designed to be attached to the underside of a larger object and used to move it. Attached to the base of device-moving equipment, caster wheels provide mobility for these objects. They make it possible to move heavy objects with less force. Caster wheels require routine maintenance to extend their service life.
