🏗️ Buyers Guide: BilJax vs. Safway Scaffolding Frames
When choosing scaffolding frames, two names come up more than any others: BilJax and Safway. These are the most widely recognized scaffolding systems in North America, and understanding their differences helps contractors, rental yards, and construction crews pick the right system for their projects.
This guide explains the history, frame types, lock systems, spacing, and walkthrough options—and provides practical advice on how these scaffolds are best used today.
🔹 A Brief History of BilJax & Safway Frames
- BilJax (founded in 1947 in Archbold, Ohio) built its reputation on lightweight yet durable yellow scaffolding frames. BilJax frames are often seen in small to mid-sized projects, drywall installations, and general contracting.
- Safway (founded in 1936 in Milwaukee, Wisconsin, now part of BrandSafway) became known for heavy-duty blue scaffolding with a stronger load rating, favoured by industrial contractors and larger commercial jobs.
Over time, both systems became industry standards. While the brands have merged and evolved, the frame designs, lock styles, and spacing differences still define how these systems are used today.
In practice, Safway scaffolding frames tend to use slightly thicker and wider steel tubing compared to BilJax, which can translate to marginally higher rigidity and durability under load. However, industry professionals often note that the real-world differences are subtle—most contractors focus on fit, locking mechanisms, and project type rather than raw strength alone.
🔹 Ladder Frames
The most common type of frame is the ladder frame, featuring rungs welded between vertical legs.
- BilJax Ladder Frames
- Typically lighter and narrower.
- Easier for interior projects and residential contractors.
- Rungs are closer together, which helps workers climb safely.
- Safway Ladder Frames
- Heavier gauge steel, wider frame profiles.
- Preferred for large-scale, heavy-duty construction.
- Slightly different rung spacing, which affects interchangeability with BilJax.
🔩 Lock Systems & Spacing
- BilJax Locks
- Candy Cane (C-locks), hook-and-pin design.
- Lock spacing: 27.75″ center-to-center.
- Braces sit closer together, giving tighter vertical alignment.
- Safway Locks
- Flip or drop locks, heavier-duty connections.
- Lock spacing: 48″ center-to-center.
- Fewer brace points, faster setup for large projects.
👉 Because of this difference, cross braces are not interchangeable between BilJax and Safway frames. Even if the tubing looks similar, the geometry won’t line up.
🔹 Frame Spacing
Spacing between rungs and frames is another key difference:
- BilJax – typically 6’4” frame heights with 4’ to 5’ rung spacing.
- Safway – commonly 5’ frame heights, giving contractors more flexibility in stacking and bracing.
Because of this, mixing BilJax and Safway frames on the same project is not recommended unless specifically engineered for compatibility.
🔹 Walkthrough Frames
When workers need to move freely through a scaffold structure, walkthrough frames are the solution.
- BilJax Walkthrough Frames
- Taller and narrower profile.
- Designed for general contractors and lighter-duty work.
- Safway Walkthrough Frames
- Wider openings, stronger steel.
- Best for masonry, stucco, and industrial projects where multiple trades need clear access.
🔹 Best Uses Today
- BilJax – Excellent for residential, drywall, painting, and light construction. Lighter frames mean easier handling.
- Safway – Ideal for commercial, masonry, industrial, and heavy-duty projects. Built to withstand greater loads and more wear.
- Walkthrough Frames – Perfect for jobs with multiple workers moving underneath scaffolding, such as bricklaying or exterior finishing.

❓ FAQ: BilJax vs. Safway Scaffolding
Q1: Can I mix BilJax and Safway frames?
Not recommended. The frame heights, rung spacing, and lock systems differ. Mixing could create unsafe load paths unless a professional engineer approves the setup.
Q2: Which is better for heavy-duty use?
Safway frames are generally stronger and better suited for masonry and industrial projects.
Q3: Which is easier to handle for small contractors?
BilJax frames are lighter and often preferred by drywallers, painters, and remodelers.
Q4: Are the lock systems interchangeable?
No. BilJax uses candy cane style C-locks with 27.75 inch spacing, while Safway uses flip locks with 48 inch spacing. Because of these differences, braces and frames from the two systems are not compatible.
Q5: What is the typical lifespan of a scaffolding frame?
With proper storage and maintenance, both BilJax and Safway frames can last 10–20 years in rental fleets or contractor use.
