 OUR PRODUCING PROCESS:
        1. Tooling (Mold) design and Manufacture.
        2. Manufacture the parts according to the Stamping Machine.
        3. Riveting, Welding or Screw tap according to Customer's require.
        4. After finish manufacture process we will test the parts by the Image measurement instrument, Caliper,
        Angel Gage etc.
        5. After make sure all the dimension can reach customer's require, we will make the surface treatment 
        process.
        6. After finish surface treatment we will testing all the parts by worker so that we can make sure the 
        parts which we sell is 100% qualified.
        7. After finish testing we will pack the parts by Vacuum Package Machine.




         Quality control:
         * We have specialized QC testers to check the quality of the products according to different customers
         requirement. Usually, it's a random inspection, and we also offer 100% inspection at a reasonable price
         if required.
         * We have IQC to check the dimensions and surface of the incoming material
         * We have PQC to inspect full-course during the manufacturing processing
         * We have FQC to inspect all the anodizing/plating and other finishes products from our supplier and
         proceed with the professional quality and appearance inspection before shipping.

Packaging & Shipping

Delivery:
1. Production: For full container, normally we need 20-30 days after receiving the customer's down payment.
2. Transportation: It depends on the destination charge port.
3. Negotiation is needed for special requirements. 


 

 

FAQ

1. What is a Square Column Shuttering Clamp?
A Square Column Shuttering Clamp, commonly called a Column Ring Clamp or Column Formwork Clamp, is a specialized, adjustable steel clamp designed specifically to secure the four-sided formwork (shuttering) for square or rectangular concrete columns. It applies uniform, high-pressure clamping force on all four sides simultaneously to withstand the lateral pressure of wet concrete, ensuring precise dimensional accuracy and preventing bulging or misalignment.

2. What are the key advantages of using a column ring clamp system?
High Precision & Accuracy: Ensures perfectly square/rectangular columns with consistent dimensions and sharp, clean corners.

Rapid Assembly & Stripping: The modular, single-unit design is significantly faster to install and remove than assembling individual walers and tie rods for each column.

High Reusability & Durability: Made from heavy-duty steel, it can be reused hundreds of times across projects.

Labor & Cost Efficiency: Reduces labor time and eliminates the need for numerous loose components (ties, nuts, washers, wedges).

Clean Finish: No through-tie holes required, resulting in a smooth, unblemished concrete surface that requires minimal patching.

3. What materials and specifications are your clamps made from?
Our clamps are engineered for maximum strength and longevity:

Main Frame: High-Tensile Carbon Steel (Q345B/S355JR).

Adjustment Mechanism: Grade 8.8 Steel Threaded Rods and Forged Steel Wedges or Lever Handles.

Pressure Points/Heads: Hardened Steel for wear resistance at contact points with the formwork.

Standard Finish: Hot-Dip Galvanized (HDG) for superior corrosion resistance in outdoor site conditions.

Alternative: Electro-galvanized or painted finishes available.

4. What column sizes (dimensions) do your clamps accommodate?
We offer a versatile range to cover common and large column sizes:

Adjustable Range: Our standard models typically adjust to fit columns from 150x150mm (6"x6") up to 1200x1200mm (48"x48") and beyond.

Fixed Sizes: Also available for high-volume projects requiring a specific, repetitive column size.

Custom Sizes: We can design and manufacture clamps for any specific square or rectangular dimension upon request.

5. How is the clamping force applied and adjusted?
We offer two primary adjustment systems for different user preferences:

Wedge & Pin System (Most Common):

Place the clamp frame around the assembled column formwork.

Insert the steel pin through aligned holes in the overlapping clamp arms.

Drive the tapered steel wedge firmly with a hammer to apply and lock the precise tension.

Threaded Screw System:

Position the clamp.

Turn the four corner screw mechanisms evenly with a wrench to achieve uniform pressure on all sides.
Both systems provide excellent, reliable clamping force.

6. How do I request a quotation or technical consultation?
For a precise quote and recommendation, please provide:

Column Dimensions (width x depth).

Maximum Column Height & Concrete Pour Rate.

Type of Formwork Panels being used.

Estimated Quantity of clamps required.

Project Location (for shipping and standard reference).

7. Are they compatible with different formwork panel types?
Yes. Our column clamps are universal and work effectively with:

Plywood/Multiplex Panels (with timber or light steel battens)

Steel Frame Panels

Plastic Formwork Systems

Aluminum Formwork
The clamp presses against the panel's stiffening members (walers/battens), not directly on the sheathing.

8. What is the recommended spacing between clamps vertically?
Vertical spacing is crucial for safety and quality and depends on:

Concrete Pour Pressure (determined by pour rate and column height).

Strength of the Formwork Panels.
As a general guideline, spacing often ranges from 400mm to 800mm center-to-center. Our technical team can provide specific spacing recommendations based on your project parameters.

9. What is your MOQ (Minimum Order Quantity)?
Standard Adjustable Models: MOQ 50 sets.

Fixed Size / Large Project Order: MOQ 100 sets.

Custom Designed Clamps: MOQ 200 sets (due to tooling/setup).

Samples: Available for on-site testing and evaluation.

10. What is the production lead time?
Samples: 10-15 working days.

Standard Order (from stock/semi-finished): 20-30 working days.

Custom Size / OEM Order: 35-45 working days after final drawing approval.

11. Do you provide installation instructions or technical drawings?
Yes. We provide comprehensive support materials with each order:

Detailed Installation Manual with step-by-step photos.

Assembly & Stripping Procedure.

Technical Drawings (DWG, DXF, PDF) for project submittals.

Load/Span Tables for engineer verification.
