Disc-type Scaffolding
Disc-type scaffolding, also known as “disc-type scaffolding,” is a temporary support or work platform structure constructed primarily from hot-dip galvanized steel pipes. It is assembled using vertical poles with built-in “disc-type joints” and horizontal/diagonal poles with plugs. Its core innovation lies in the “disc-type joint design”—discs are welded to the vertical poles at regular intervals (usually 500mm). The end plugs of the horizontal and diagonal poles plug directly into the holes in the discs and are quickly locked with wedge pins, eliminating the need for additional fasteners and achieving a “plug-and-lock” assembly. Compared to traditional fastener-type scaffolding, disc-type scaffolding offers significantly improved joint torsional stiffness and overall stability. Its highly standardized components accommodate support requirements of varying spans and heights, allowing for working heights exceeding 50 meters (higher heights can be customized for special projects).

Aluminum Alloys Mobile Scaffolding with Steel Pipes
Mobile scaffolding, also known as “movable scaffolding,” is primarily constructed of steel pipes, aluminum alloys, and other materials. These components are assembled through connectors to create a stable frame structure. Equipped with universal or fixed wheels with brakes, these temporary work platforms can be moved on level ground. Mobile scaffolding provides a safe and stable platform for workers working at height, while also supporting loads such as tools and materials. Operating heights typically range from 2 to 15 meters (higher with custom designs). Unlike traditional fixed scaffolding (such as floor-standing or cantilever scaffolding), it eliminates the need for embedded anchors in the ground, simplifying installation and movement.

M20 Threaded Bar Specification Reference
The related product list helps you compare China M20 Threaded Bar Manufacturer, Factory & Suppliers by actual product direction rather than keyword wording alone. Check whether each product supports bulk purchasing evaluation, then use the table below to prepare a clearer RFQ.
| Criterion | What To Check | Why It Matters | Buyer Tip |
|---|---|---|---|
| Material Grade | Confirm steel grade (e.g., 4.8, 8.8, 10.9 or stainless A2/A4) | Grade determines load capacity and corrosion resistance for your application | Request mill test certificates matching your specified grade before bulk order |
| Thread Specification | Verify M20 pitch (coarse 2.5mm or fine 1.5mm) and thread tolerance class | Wrong pitch causes assembly failure and costly rework on-site | State ISO metric standard (ISO 965) in your RFQ to avoid ambiguity |
| Bar Length & Cut Tolerance | Confirm available lengths and cutting tolerance (±1mm or tighter) | Inconsistent lengths disrupt installation schedules in bulk projects | Request a sample cut piece to verify tolerance before committing to full order |
| Surface Treatment | Specify finish: plain, zinc-plated, hot-dip galvanized, or black oxide | Coating choice directly affects corrosion life and compliance with project specs | Ask for coating thickness report (e.g., microns for zinc) with each shipment batch |
| Packaging & Export Marking | Confirm bundle weight, pallet spec, and export carton labeling requirements | Improper packaging causes transit damage and customs clearance delays | Provide your destination port and Incoterms in RFQ to get accurate packing quotation |
How To Choose m20 threaded bar Supplier
When comparing a China M20 Threaded Bar Manufacturer, Factory & Suppliers, the most direct evaluation points are material grade, thread standard, bar length, finish, and whether custom cutting or packaging is available. A useful inquiry goes beyond asking for a catalog — it states quantity, destination, application, and any fixed specifications that cannot change.
This page is organized around a specification checklist and quality review angle, so you can convert a broad product search into targeted questions that give suppliers enough context to respond with accurate pricing and lead times.
Before reaching out to any China M20 Threaded Bar Manufacturer, Factory & Suppliers, document the fixed requirements for your order: thread standard (metric coarse or fine), material grade (carbon steel, stainless, or alloy), surface treatment (plain, zinc-plated, hot-dip galvanized), and whether bars need to be cut to specific lengths. These details determine whether a supplier's standard range matches your project or whether custom production is required.
For bulk purchasing evaluation, also confirm packaging requirements early. M20 threaded bar is typically bundled or packed in cartons, but export orders may require specific labeling, pallet configuration, or moisture protection. If your destination has import certification requirements, note those in your inquiry as well.
When preparing your RFQ, include estimated quantity range, required lead time, target delivery port, and your approval process for samples or inspection. Suppliers who receive this information upfront can provide more accurate quotations and flag potential lead-time or MOQ constraints before they become problems.
When reviewing supplier responses, prioritize those that address your stated specifications directly and ask relevant follow-up questions. A supplier that confirms material certifications, offers test reports, and clarifies packaging options is generally easier to qualify than one that responds with only a general product list and a price per kilogram.
| Criteria | Importance | Description | Example Options |
|---|---|---|---|
| Material Grade | Critical | Determines load capacity and corrosion resistance for the application environment | Carbon steel 8.8 vs. Stainless 316 |
| Thread Standard | High | Must match mating nut and coupling specifications to ensure assembly compatibility | ISO metric coarse M20×2.5 |
| Surface Treatment | High | Affects corrosion protection level and suitability for indoor or outdoor installation | Hot-dip galvanized vs. zinc plated |
| Custom Length Tolerance | Medium | Supplier ability to cut and supply non-standard lengths within specified dimensional tolerance | Cut-to-length ±1mm tolerance |
| Export Packaging | Medium | Packaging format impacts transit safety, unloading efficiency, and warehouse handling at destination | Palletized cartons with stretch wrap |

What is the strongest type of threaded rod?
The strongest type of threaded rod depends on what "strongest" means for the application. If tensile strength is the main requirement, quenched-and-tempered alloy steel threaded rod is usually stronger than standard carbon-steel rod or common stainless-steel rod. In demanding industrial applications, high-strength alloy-steel grades such as ASTM A193 Grade B7 or selected quenched-and-tempered structural fastener grades may be specified. However, the highest tensile-strength threaded rod is not automatically the best...
What Is a Booker Rod? Uses, Materials, and Selection Guide
A booker rod is a fully threaded metal rod used for fastening, suspension, bracing, adjustment, and structural support. The term is commonly used in Australia and some construction markets to describe what is also called threaded rod, allthread, threaded bar, or studding. Unlike a standard bolt, a booker rod has threads along most or all of its length. This allows nuts, washers, couplers, brackets, and other fittings to be positioned...
