Complete Product Description
What You Get
Every clamp is stamped from grade Q235 carbon steel, then electroplated with a zinc layer of 8 to 12 microns thickness. This coating meets the requirements of ASTM B633 for service condition 2, giving you a salt spray resistance of 72 hours before white rust appears and up to 96 hours before red rust forms – a reliable safeguard for typical indoor plumbing environments. The threaded nut is manufactured to ISO 965‑1 tolerance class 6H, ensuring a smooth, secure fit on both M8 and M8 threaded rods. Available pipe sizes cover the most common drainage and supply lines: 15, 20, 25, 32, 40, 50, 63, 75, 90, and 100 mm outer diameter.
Why This Design Works
The combination thread feature is the standout. Instead of choosing between M8 and M10 supports, you get one clamp that works with either rod size a small detail that cuts your SKU count nearly in half. The screw length has been optimized so that the clamp accommodates the full size range without requiring different bracket bodies. Field tests show that installation time drops by about 30% compared to traditional two‑piece hangers because you only need to slide the rod through the top nut and tighten.
Where You Can Use It
These brackets are suitable for suspending metal pipes, PVC, CPVC, and PEX tubing in water supply lines, drain and vent stacks, sprinkler systems, and exposed overhead piping in mechanical rooms. They are not recommended for outdoor or highly corrosive settings such as coastal areas or chemical plants, unless you choose a hot‑dip galvanized or stainless steel option from our custom range.
Performance Numbers You Can Rely On
- Material hardness: HRB 65–75
- Tensile strength of the steel: ≥ 370 MPa
- Maximum static load capacity: 220 kg for the smallest size, scaling down slightly for larger diameters – consult our engineering table for exact values
- Coating adhesion: passes the cross‑hatch test per ASTM D3359
- Operating temperature range: –20 °C to +80 °C (zinc coating remains stable within this band)
Common Field Issues – Addressed
Slow assembly and extra labor costs
Many contractors still use separate rod couplers and saddle clamps, which require aligning multiple loose parts overhead. Our one‑piece nut and ring construction lets you pre‑assemble the clamp on the ground, then simply thread it onto the rod. For a typical 100‑point installation, this can save one to two man‑hours.
Overstocked inventory and wrong‑size errors
When you carry two separate clamp types for M8 and M10 rods, you inevitably end up with unused leftovers of one size. Our dual‑compatibility design reduces that waste. Stock just one part number per pipe diameter, and you are always ready for either rod system.
Rust problems in humid mechanical rooms
Standard zinc coatings of 5 microns or less often fail after a few months in high‑humidity environments. Our 10‑micron average thickness, combined with a clear chromate passivation, pushes the corrosion resistance well beyond ordinary electroplated fasteners. Independent lab reports confirm 96 hours of neutral salt spray without base metal corrosion.
Loose grip and pipe movement
Cheaper clamps tend to deform under load or have uneven inner diameters. Our O‑ring shape is hydroformed with a precision mandrel, giving a roundness tolerance of ±0.3 mm. The clamping force is evenly distributed around the pipe, which prevents point loading and keeps the pipe stable under vibration from pumps or flow turbulence.
Our Production Facility – What We Can Deliver
We run a dedicated pipe support production line with three 120‑ton presses, two automatic tapping machines, and a barrel plating line that processes 5,000 kg of parts per shift. The workshop covers 4,800 square metres and operates under ISO 9001:2015 quality management. Every batch is sampled for coating thickness using an X‑ray fluorescence analyser, and we perform a torque test on 5% of each lot to verify the thread strength.Our monthly output for this clamp series is 120,000 pieces, with a typical lead time of 15 to 20 working days for new production orders. For standard sizes that are regularly stocked, we can ship within 3 business days.
Customisation – We Don't Just Offer Standard Options
While our standard clamp meets most indoor needs, we are set up to handle modifications:
- Non‑standard diameters – If you need 110 mm, 125 mm, or even metric sizes not listed, we can re‑tool the forming die. Minimum order quantity for custom sizes is 3,000 pieces.
- Different material grades – For higher strength or better weldability, we can switch to Q345B steel. For food‑processing or pharmaceutical environments, we offer 304 and 316L stainless steel versions.
- Coating choices – Beyond electroplated zinc, we provide hot‑dip galvanizing (minimum 60 microns) for outdoor use, or zinc‑aluminium flake coating (like Geomet) for up to 1,000 hours of salt spray resistance. We can also apply a yellow or black passivation if required for colour coding.
- Packaging customisation – We can bag individual clamps with labels, shrink‑wrap sets of 10, or bulk pack in reinforced cartons. Pallet loads are stretch‑wrapped and strapped to ISO shipping standards.
Shipping and Delivery
We keep a safety stock of around 30,000 pieces covering the most popular sizes – 20, 25, 32, and 40 mm. Orders for these can be dispatched within 48 hours of payment confirmation. For larger quantities, we coordinate with sea freight forwarders for container loading, and we also work with DHL and UPS for express shipments if you need samples or urgent small orders.Packaging is designed to survive rough handling: inner boxes are lined with corrugated cardboard dividers to prevent metal‑to‑metal rubbing, and outer cartons are double‑walled. For full pallets, we use edge guards and corner protectors, and each pallet is clearly marked with the part number, quantity, and batch traceability code.We have shipped to over 20 countries in the last year, including the United States, Canada, Australia, the UK, Germany, and Southeast Asian markets. Customs documentation and commercial invoices are prepared in English, and we can arrange insurance coverage on request.
Get in Touch
If you need a quote, a sample pack, or technical drawings for your project engineer, just send us a message. We can also provide load deflection curves and installation torque recommendations. Let us know your pipe diameter, rod size, and order quantity we will get back to you within one working day.
