Walk Through Frame Scaffolding System
Walk Through Frame Scaffolding System is one of the most widely used and mature scaffolding solutions in the construction industry. The system is mainly composed of walk-through frames and mason frames, also commonly referred to as H-frames or ladder frames, allowing workers to move freely during operation.
Designed for high cost performance and flexible site use, frame scaffolding is suitable for most general construction projects, especially small to medium-scale works such as building construction, renovation, and maintenance.

Walk Through Frame Scaffolding Components
A complete walk through frame scaffolding system normally contains more than the main frames.
Walk Through Frames---These are the main vertical uprights that actually carry the weight of the whole scaffold structure.
Cross Braces---These are the diagonal bars that tie neighboring frames together, giving the structure its side-to-side stability so it doesn't wobble.
Joint Pins---Joint pins or spigots connect frames vertically.
Base Jacks---Adjustable base jacks allow the scaffold to be leveled and provide support at the bottom of the structure.
Scaffold Planks---Steel planks or walk boards provide the working platform.
Guardrails---Guardrails provide edge protection around platforms.
Toe Boards---Toe boards can aviod tools and materials falling.
Side Bracket---Side brackets can extend the working platform width.

Surface treatment Options
Hot-Dip Galvanized Scaffolding
Hot-dip galvanizing is achieved by fully immersing steel components into molten zinc, which provides a thicker zinc coating and is suitable for outdoor construction for anti rust.
Application: It's used for outdoor, coastal, or humid construction environments, ensuring long service life.
Pre Galvanized Scaffolding
Pre-galvanized steel tube is commonly used for economical frame scaffold production. The steel tube is galvanized before frame fabrication.
Application: It's used for indoor or short-term projects.
Powder Coated Scaffolding
Powder coating spray resin-based powder onto the scaffold surface, and creates a uniform, wear-resistant coating. It's durable and long service life.
Application: It's suitable for outdoor environment.
Painted Scaffolding
Painted walk through frames can support customers choose different colors and price is cheaper.
Application: It's suitable for indoor or short-term projects.

Masonry Construction
Walk through frames can be used for bricklaying, blockwork and exterior wall construction.
Plastering and Stucco
The working platform provides access to exterior walls for plastering, rendering and stucco work.
Painting
Contractors can use frame scaffolding to access exterior and interior wall surfaces.
Residential Construction
Walk through frames are suitable for many residential building and renovation projects.
Commercial Construction
The system can be configured for office buildings, retail buildings, warehouses and other commercial projects.
Industrial Construction
Depending on the required design, frame scaffolding can also be used for industrial maintenance and construction work.
Building Maintenance
Essentially, because the setup is modular, contractors can easily put together temporary work platforms when they need to tackle maintenance.
