Diagonal Braces
Ringlock diagonal braces, also called scaffold braces, cross braces, or sway braces, provide essential lateral stability to ringlock scaffold structures. They prevent racking, deformation, and collapse under wind loads, dynamic loads from worker movement, and eccentric loading conditions. Our diagonal braces consist of high-strength Q235 steel tubes with drop-forged wedge heads at both ends, specifically designed to engage with the rosette slots on vertical standards at diagonal angles.
As a professional diagonal brace manufacturer based in Nanjing, China, LuckyScaffolding produces braces in standard configurations for common bay and lift combinations. Custom brace lengths are available for non-standard scaffold configurations — simply provide your bay width and lift height, and our engineers will calculate the exact brace length required using the Pythagorean theorem.
Our ringlock diagonal braces are manufactured from Q235 structural steel tube with an outer diameter of 42.2mm (standard duty) or 48.3mm (heavy duty). All braces are hot dip galvanized to ISO 1461 with minimum 80 micrometers zinc coating. The wedge heads are drop-forged from high-carbon steel and feature captive wedge pins that cannot be lost during assembly.
Diagonal bracing is mandatory on all faces of a ringlock scaffold under EN 12810 and OSHA regulations. Without proper bracing, the scaffold lacks the necessary lateral stiffness to resist horizontal forces and is unsafe for use. We supply diagonal braces to scaffold contractors, rental companies, and construction firms in over 60 countries.

Frequently Asked Questions
How do I determine the correct diagonal brace length for my scaffold?
Brace length is calculated using the Pythagorean theorem based on your bay width and lift height. For example, a 2.0m bay with 2.0m lift requires a brace of approximately 2.83m. We provide a comprehensive brace length chart, or our engineers can calculate exact lengths for your specific configuration.
Are diagonal braces mandatory on ringlock scaffolding?
Yes, diagonal bracing is mandatory on all faces of a ringlock scaffold under EN 12810, BS 1139, and OSHA regulations. Without braces, the scaffold lacks lateral stability and cannot safely resist wind loads or horizontal forces. Using an unbraced scaffold is a serious safety violation.
Can I use tube-and-fitting braces with a ringlock system?
No, ringlock diagonal braces have specifically designed wedge heads that engage with the rosette slots. Tube-and-fitting braces use couplers that are not compatible with the rosette connection. Only ringlock-compatible braces should be used.
What is the difference between 42.2mm and 48.3mm braces?
42.2mm braces are the standard duty option, suitable for most access scaffolding applications. 48.3mm heavy-duty braces offer higher stiffness and load capacity, recommended for heavy shoring towers, high-wind areas, and platforms supporting heavy materials or equipment.
How many braces do I need for a typical scaffold tower?
As a general rule, every face of the scaffold should have diagonal bracing in every other bay. A typical 3-bay x 3-lift tower requires approximately 12-16 braces. Our engineers can provide exact brace quantities based on your scaffold layout drawing.
Can you make custom-length diagonal braces?
Yes, we can manufacture braces in any length from 0.5m to 4.0m. For custom lengths, please provide your bay width and lift height, and we will calculate and produce the exact brace lengths needed.
How are diagonal braces packed for shipping?
Braces are nested together in bundles of 25 or 50 pieces, secured with steel strapping. Because braces are long and irregularly shaped, we carefully pack them to maximize container space while preventing damage during transit.
