        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.

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 column clamp?
A column clamp is a securing device designed to attach scaffolding, formwork, safety systems, or other equipment to a vertical structural column. It provides a strong, stable, and temporary connection point without damaging the column.

2. What are the main types of column clamps?

• Scaffolding Column Clamp (Right-Angle Clamp): Used to connect scaffold tubes at a 90-degree angle to a column. Often has a single bolt for tightening.

• Formwork Column Clamp (Beam Clamp): A heavy-duty clamp, often made of steel, used to secure concrete formwork panels or walers (horizontal braces) around a column before pouring concrete.

• Universal/Adjustable Column Clamp: Features adjustable jaws or links to fit a wide range of column sizes and shapes (square, rectangular, round).

• Girder Clamp: Similar but often used for attaching to the flanges of I-beams rather than columns.

3. What are column clamps used for?

• Scaffolding: Creating access platforms around columns or building tie-in points for scaffold stability.

• Concrete Formwork: Holding together the molds (shuttering) for casting concrete columns.

• Temporary Support & Bracing: Providing lateral support to columns during construction or renovation.

• Fall Protection: Anchoring lifelines or guardrail systems to columns.

• MEP (Mechanical, Electrical, Plumbing): Supporting pipes, ducts, or conduit runs from a column.

4. What materials are column clamps made from?

• Steel (Drop-Forged or Cast): Most common for heavy-duty applications (formwork, scaffolding). Often hot-dip galvanized for corrosion resistance.

• Aluminum: Lightweight alternative for lighter-duty scaffolding or access applications.

• Stainless Steel: Used in corrosive environments like chemical plants or coastal areas.

5. How do I choose the right column clamp?
Consider these key factors:

• Column Size & Shape: Ensure the clamp's capacity range matches your column's dimensions.

• Load Rating (SWL - Safe Working Load): The clamp must be rated for the intended load (workers, materials, concrete pressure). Never exceed the SWL.

• Application: Match the clamp type to the task (e.g., formwork clamps are much stronger than light-duty access clamps).

• Material & Finish: Choose based on environment (e.g., galvanized steel for outdoor use).
  

6. How do you properly install and use a column clamp?

1. Inspect: Check the clamp for damage, cracks, or wear before use.

2. Position: Place the clamp securely around the column. Ensure contact surfaces are clean and free of debris or loose material (e.g., concrete form release agents).

3. Tighten: Tighten the bolt(s) or fastener evenly and securely using the correct tool (usually a spanner/wrench). Follow the manufacturer's specified torque if provided.

4. Attach Load: Connect the scaffold tube, formwork panel, or other equipment to the clamp's attachment point (e.g., cup, stud, pin).

5. Re-check: After applying load, re-tighten if necessary, as some settling may occur.

7. What are critical safety precautions?

• Never overload the clamp. Know the SWL.

• Ensure the column is structurally sound and capable of bearing the imposed loads.

• Always use the clamp as intended by the manufacturer. Do not modify it.

• Use a positive locking mechanism (like a nut and bolt) that cannot vibrate loose. Self-locking nuts are common.

• Perform regular inspections for deformation, cracks, or thread damage.
  

8. How do formwork column clamps work?
For concrete columns, two or four clamps are typically used per pour level. They are placed opposite each other around the formwork panels and connected via threaded tie rods (through holes in the panels) or by bearing directly on walers. Tightening the clamp nuts applies uniform pressure, containing the wet concrete's hydrostatic pressure and ensuring a straight, square column.

9. What is the difference between a column clamp and a beam clamp?

• Column Clamp: Designed to fully encircle a (usually) concrete or square column. The load is often applied perpendicularly.

• Beam Clamp (Girder Clamp): Typically hooks onto the bottom flange of an I-beam or H-beam. The primary load is usually vertical (suspended). Some are designed for horizontal loading as well.

10. Can column clamps damage the column?
When used correctly on structurally sound columns, they should not cause damage. However, excessive overtightening on concrete columns can cause spalling or cracking at the edges. Using protective pads (e.g., hardwood or polymer) between the clamp and a finished concrete surface is a common best practice.
