Scaffolding

For your crew or for you, having the right scaffolding set on site isn’t just about reaching where you need to, it’s about working and moving safely, efficiently, and on schedule. A solid scaffolding system gives you a stable work platform for everything from masonry and siding to general repairs so crews can get to work faster. When you’re buying scaffolding, durability, ease and flexibility of set up matter most. Having equipment that can handle hard daily use, adjust to different heights, and bring down cleanly for transport or storage. A quality scaffolding set means fewer slowdowns, safer work conditions, and a setup you can rely on, job after job. Shop this selection of scaffolding sets and pieces that feature industry leaders Metaltech.

Scaffolding Equipment Frequently Asked Questions:

What are the different scaffolding pieces?
The main types of scaffolding are single scaffolding, double scaffolding, cantilever scaffolding, suspended scaffolding, trestle scaffolding, steel scaffolding, patented scaffolding, wooden/bamboo scaffolding, tube and clip scaffolding and kwikstage scaffolding. Each style primarily consists of a mixture of the following parts:
  • Standards: Vertical scaffolding supports
  • Ledgers: Horizontal scaffolding supports
  • Putlog Holes: Added holes used for anchoring to the structure
  • Rakers: Support ties for scaffolding
  • Cross Braces: Scaffolding support pieces
  • Platform: Solid floor-type piece to walk/stand on
  • Wires & Chains: Suspend a scaffolding platform from a structure’s roof
  • Couplings: Lock supports firmly together
  • Guard Railings: Enclose scaffolding edges for added safety
What are the safety items I should have when using scaffolding?
If the scaffolding is more than 10 feet off the ground, all people using the system must use personal fall arrest systems or guardrails. Single-point and two-point adjustable scaffolds also require the protection of guardrails and personal fall arrest systems. Follow all load-bearing capacities of the scaffolding system. OSHA requires scaffolds to support 4 times the maximum intended load without failure. Follow manufacturer’s instructions while constructing scaffolding and avoid power lines by a minimum of 10 feet in most instances (situational adjustments to distances may apply). Since rules and regulations are continually revised and updated, always consult current administrative interpretations and decisions by OSHA and the other governing organizations in your area for the most recent laws and regulations prior to the use of scaffolding.
Is there a weight limit for scaffolding?
There are 3 categories of load-bearing scaffolding planks as defined by OSHA. The weight rating for each category is outlined below and is based on the weight being applied uniformly across the scaffold planks.
  • Light-duty scaffolding: 25 lbs. per sq. ft.
  • Medium-duty scaffolding: 50 lbs. per sq. ft.
  • Heavy-duty scaffolding: 75 lbs. per sq. ft.
Multiply the base rating — 25, 50 or 75, depending on the duty designation of the model — by the square footage of the model’s work surface. For example, light-duty scaffolding with a 30-square-foot platform would be 25 x 30 (25 base rating x 30 sq. ft.) which translates to a rating that safely accommodates no more than 750 lbs. total weight (total weight must include a combination of all tools, materials and people on the plank).
What are spme tips for putting together and taking apart scaffolding equipment?
Refer to the manufacturer’s owner's manual for best practices. If no instructions are available, here are some general rules and steps to follow.

ASSEMBLY:

Step 1: Level the ground at the assembly space. Find dry, solid ground so no slipping or sinking takes place. Scout the area for hazards or obstacles and make sure you will be able to avoid them when the scaffolding is assembled.

Step 2: Place 1ft. x 1ft. foot pads under each bottom scaffolding foot, especially when assembling on soft or sandy ground.

Step 3: Each vertical frame should be locked into a foot pad. Shakey or unsteady frames should be braced or secured with tie wire. (NOTE: Do not use tie outs to brace diagonal bars.)

Step 4: Place plank grade lumber (Do NOT use plywood or wood with knots) onto the scaffolding. Ensure at least a 4” overlap at each end of the frame.

Step 5: Raise height of assembly by locking in more vertical scaffolding beams and attaching diagonal braces in a crisscross pattern on the front and back of the scaffolding to add stability. The braces also provide a rail for added security. Top with another piece of plank grade lumber, then continue the building process following the same sequence of steps until the scaffolding is as high as needed.

DISASSEMBLY:

Step 1: Work in reverse order of the assembly process. Start by unclipping or unlocking the top scaffolding bars.

Step 2: Unclip or remove the diagonal braces.

Step 3: Remove the planks of lumber used as a floor for the top level. (Ask for assistance as lumber may be heavy working over your head.) Make sure you are on the next level down while removing planking.

Step 4: Unlock or unclip the next set of vertical scaffolding and continue to work your way down the scaffolding assembly in the manner described in steps 1 through 3 until you reach the bottom.

Step 5: Remove all foot pads from the bottom of the scaffolding—and you are finished.

NOTE: At least 2 people are recommended for assembly and disassembly of scaffolding. Please check all state rules, regulations and special requirements prior to assembly.
When should scaffolding equipment be checked for maintenance needs?
As of the writing of this answer, OSHA requires the general contractor or user of scaffolding to inspect scaffolding equipment under the following schedule: after installation but prior to the first use. Then again at intervals of no more than every 7 days thereafter. Scaffolding inspections and maintenance are also required following any circumstances that are capable of jeopardizing the safety of the equipment or installation (i.e., ground shifts/sink holes, high winds, hailstorms, etc.). Guidelines are periodically updated in response to new information. Please consult OSHA’s website for the latest rules and regulations.
