Frame Scaffolding – Choosing the Right Frame Style and Type
We carry three different styles of frames: S-Style (Blue), W-Style (Red), and BJ-Style (Yellow). These are the industry standard styles of frame in the United States. The S-Style is interchangeable with Safeway frames, the W-Style is interchangeable with Waco frames and the BJ Style is interchangeable with Bill Jax Style frames. All if these styles have been in use for many decades so their design and functionality is tried and true. Because of this, you should be hesitant to use a scaffolding style that is not one of these styles.
One of the biggest determining factors in choosing your frame style is whether it will match your existing scaffolding. The biggest differences between the three different styles are the leg diameters (meaning they take different size pins), pin hole locations (meaning the location of the pin holes are at different angles in relation to the horizontal axis of the scaffolding frame), and styles of cross brace locks. The pins are what connect the scaffolding frames together vertically and cross braces connect the scaffolding together horizontally.
Safeway-Style Blue Scaffolding
This style our overall most popular style of frame. It fits Safeway Style Frames and is used extensively in the southern and southwestern parts of the United States. The full size frames are 6’4” tall and it takes a 1-7/16” coupling pin (USA-104 Coupling Pin), has pin holes at 45 degrees to the horizontal member, and drop locks to keep the cross braces in place.
Waco-Style Red Scaffolding
This style of frame scaffolding has full size frames that are 6’7” tall and takes a 1-3/8” coupling pin (USA-100 or 103 coupling pins) with pin holes at 90 degrees to the horizontal member, and candy cane style drop locks.
Big Jax-Style Yellow Scaffolding
This style of frame scaffolding has full size frames that are 6’6” tall and takes a 1-3/8” coupling pin (SWS-107) with pin holes at 90 degrees, and C Locks to keep the cross braces in place.
Types of Frame Scaffolding
Walk Thru Frames are often used when you need a long working platform and the ability to traverse the length of that platform by walking through the frames such as during masonry construction on a long wall.
Ladder frames are often used in constructing scaffolding towers, interior applications and where more precise adjustments to the working platform height is needed. Ladder frames cam also be used on the ends of a scaffolding platform in conjunction with walk-thru frames. If the rungs on the frames are less than 18” apart, the frame itself is allowed to be used as a ladder per OSHA standards. We usually recommend either a stair tower or separate bolt on ladder system be used for scaffolding access whenever possible.
Our half-high frames range from 2’ to 4’ high and are often used in interior applications where additional height is needed but where ceiling heights precludes use of a full size frame.
We carry frames that are 2’ to 3’ wide that are used for stucco, lighter duty applications, in tight spaces, interior applications or where the speed and ease of carrying and assembling smaller frames is a priority over size. Smaller frames also require less decking.
