Product Overview

Our Round Head Pins are essential components for modern aluminum formwork systems. Designed for speed and durability, these pins work seamlessly with wedge bolts to lock formwork panels securely in place. Engineered for high-pressure concrete pouring, they ensure perfect alignment and a smooth wall finish.

As critical concrete formwork accessories, our formwork pins provide the reliable connection points needed for efficient construction. The wedge and pin system allows for rapid assembly and disassembly, significantly reducing labor time and improving construction efficiency on high-rise residential, commercial, and infrastructure projects.

Technical Highlights

Precision Forged: Made from high-carbon steel (45# steel or Q235) and heat-treated to withstand the immense pressure of wet concrete. Our high strength steel round head pins for aluminum formwork provide exceptional durability and load-bearing capacity even in demanding construction environments.

Superior Finish: Yellow Zinc Plating (Galvanized) provides a thick protective layer, making the pins rust-proof and reusable across multiple construction cycles. Our yellow zinc plated formwork pins wholesale program ensures consistent quality and competitive pricing for large-scale construction projects.

Perfect Compatibility: Standardized dimensions that fit all major global aluminum formwork brands including Mivan systems, Doka, Peri, and other international formwork systems. The concrete wall formwork wedge pin system ensures seamless integration with your existing formwork inventory.

Tapered Design: The carefully engineered taper allows for easy insertion and rapid removal, significantly reducing labor time on site. The smooth surface finish prevents concrete adhesion, making cleaning and reuse faster and more efficient between pours.

Installation / Usage Tips

What are pins and wedges used for in formwork? Pins and wedges are the primary fastening system for aluminum formwork. The pin passes through aligned holes in adjacent formwork panels, while the wedge is hammered into the gap between the pin and panel to create a tight, secure connection. This system allows for rapid assembly without tools and quick disassembly after concrete curing. Our concrete wall formwork wedge pin system ensures perfect panel alignment and prevents concrete leakage.

How many formwork pins do I need per square meter? The quantity depends on your formwork system design and concrete pressure. Typically, aluminum formwork systems require 8-12 pins per square meter of wall area for standard residential construction. High-rise buildings or thick walls may require 15-20 pins per square meter. Consult your formwork engineer for project-specific calculations, or contact our team for assistance with quantity estimation.

Difference between flat head pins and round head pins: Round head pins are the most common type, providing a smooth surface that prevents concrete adhesion and allows for easy cleaning. The rounded head also provides a better striking surface for wedge installation. Flat head pins are used in specific applications where a flush surface is required or where space is limited. Round head pins are generally preferred for their versatility and ease of use.

Proper Installation: 1) Align the formwork panel holes. 2) Insert the pin through the aligned holes. 3) Position the wedge at the correct angle. 4) Hammer the wedge firmly until tight. 5) Verify the connection is secure by checking for movement. Never over-tighten wedges as this can deform the pin or damage the formwork panel.

Concrete Pouring Best Practices: Ensure all pins and wedges are properly installed and tightened before concrete placement. Check connections periodically during pouring as concrete pressure increases. Vibrating concrete can loosen connections, so verify tightness after vibration operations.

Removal and Cleaning: After concrete has cured (typically 12-24 hours for aluminum formwork), remove wedges by striking the back side or using a wedge puller. Pull pins straight out to avoid bending. Clean pins immediately after removal to prevent concrete buildup. A wire brush and water are usually sufficient for cleaning.

Storage and Maintenance: Store pins in a dry, organized manner to prevent rust and damage. Apply a light coating of oil before long-term storage. Inspect pins before each use for bending, cracks, or excessive wear. Replace any pins showing damage or significant corrosion. Proper maintenance can extend pin life to 300+ reuse cycles.
