    FAQS

    Q 1: What is the difference between a Ladder Frame and an H Frame?

    A: In the scaffolding industry, Ladder Frame and H Frame generally refer to the same type of component. They are the most famous frame scaffolding systems used in American and Latin American markets. The name "H Frame" comes from the shape of the frame when viewed from the side, while "Ladder Frame" describes the runged appearance of its vertical structure. Both are core elements used to build a stable scaffold tower.

    Q 2: What are the common applications for Ladder Frames?

    A: Ladder Frames are versatile. Primarily, they are used to support workers during building service and maintenance tasks. However, for more heavy-duty construction projects, our heavy-duty ladder frames are strong enough to support H-beams and formwork during concrete pouring operations. They are essential for providing safe access and structural support on job sites.

    Q 3: Can you customize the Frame Scaffolding based on specific project drawings?

    A: Yes, absolutely. We specialize in manufacturing all types of scaffolding frames based on customer requirements and detailed drawings. Whether you need a standard main frame or a specialized walk-through frame, we have established a complete processing and production chain. This allows us to customize dimensions, load capacities, and configurations to meet the specific needs of different markets.

    Q 4: What materials and surface treatments are available for your Main Scaffold Frames?

    A: We offer a wide range of raw material steel grades to suit different load requirements, including Q195, Q235, and Q355. Regarding surface treatment, we provide three primary options: Powder Coated, Pre-galvanized (Pre-Galv.) , and Hot Dip Galvanized (HDG) . This ensures that our main scaffold frames have excellent corrosion resistance and durability for various environmental conditions.

    Q 5: What is the complete system included in the Frame Scaffolding?

    A: The frame scaffolding system is comprehensive. Besides the main Ladder Frame or H Frame, the system typically includes Cross Braces for stability, Base Jacks and U Head Jacks for height adjustment and support, Planks with Hooks for walkways, Joint Pins for stacking frames vertically, and Staircases for access. We can supply all these components to form a complete scaffolding solution.
