Why is it used for heavy construction? It's easy for crews to build strong structures quickly and over and over again thanks to its welded rosette connection, wedge-pin lock, and standard parts. 48mm and 60mm series disc lock scaffolding are manufactured by Shandong Xingrui using Q235 steel. It can be used for outside walls, bridges, factories, and slab support. Find out how the system works, what makes it safe, and how to buy a lot of it by reading this guide. You can then choose if it fits your next project.

Stamped rosette disks are welded every 500 mm to form the modular system known as disc lock scaffolding. Ledgers, transoms, and diagonal braces connect the disks to the beams. Each joint is locked by a wedge pin. You can see that each rosette has eight holes. There are four big holes for diagonal braces and four small holes for ledgers at a 90-degree angle. You can finish building something by adding toe boards, base jacks, platforms, and guardrails. Crews can use the same bay layout over and over because each part has a set place. I think you should look at the drawings and tolerances before you place your order because different manufacturers use different terms and sizes.
The ring-type joint spreads the stress over the contact points on the rosette so that it doesn't just rest on one clamp. For the load, it starts on the platform and goes to the ledgers and transoms. It then goes to the standard through the wedge connection and to the base jack and ground. Because they are braced, the bays don't rack sideways. With our wedge-locking design, the pin stays in place in the disk thanks to gravity. It will stay put and not come out by accident while it's being used. But the link is only one part of the chain. To make sure the plan is safe, an engineer should check the scaffold's base, bay spacing, and bracing to see how much weight it can hold.
In North America, many people call this type of system "ringlock scaffolding." Both names mean the same type of rosette, but different manufacturers use wedge angles and rosette sizes that are not the same. Plain clamps and swivel couplers do not work with each other. It's easier to fix things like connections that don't line up right and angles that aren't straight now. When you use a disk lock system, it's easy and quick to connect parts, which is helpful for large layouts that are mostly the same. Unless an engineer says it's okay, don't put clamp-based and disc-based parts together. I think you should keep a few couplers on hand for small parts and build the main structure with disk lock parts.
We have a 48mm light-duty series and a 60mm heavy-duty series. It is made of Q235 steel. With the 48mm series, less heavy work can be done on the front and sides of buildings. These 60mm screws are good for building bridges and tall shoring. Rosettes with eight holes spaced 500 mm apart are used for both.
| Parameter | 48 Light Series | 60 Heavy Series |
|---|---|---|
| Tube diameter | 48.3mm | 60.3mm |
| Material | Q235 steel | Q235 steel |
| Rosette spacing | 500mm | 500mm |
| Disc holes | 8 | 8 |
| Coating | 60-80μm HDG | 60-80μm HDG |
| Vertical load capacity | Up to 30kN | Up to 50kN |
| Corrosion resistance | 10-15 years | 10-15 years |
Look at these numbers to see how our rated series is. How the scaffold is set up and how much it can hold depend on how the whole thing is built.
The ring-type joint of disc lock scaffolding is easy to put together and doesn't have any loose screws. It spreads stress evenly across its contact points. We have found that the frequency of turnover is 30% higher with these systems than with tube-and-clamp systems, and the installation time is half as long. When you change layouts for the next job, you don't have to order new parts because the accessories work with all of them. The parts' cost is spread out over many projects because they can be used more than once. Rental fleets are the ones that gain the most because each unit makes more money over time when it is used more often. If your project needs lengths or heights that aren't standard, we can also make them just for you.
For each application, the system has to do different things: 1.
Fixed connection points save the most time for these jobs because they use the same bays over and over.
Each part of a scaffolding disk lock must work well for the whole lock to work. What makes the disk resistant to shear is how well the welds are done at the rosette. The measurements are very important for how well the parts fit together and can be switched out. If the coating is thick, it will last longer. Any supplier should be able to show you certificates from steel mills, ways to check welds, and readings from a magnetic gage that show how thick the coating is. When things come in at Xingrui, we keep track of the materials and goods that go in. This way, we can always tell what the quality is. With 12 robot welders and 6 automatic lines, we can make sure that each set of welds is the same.
The Q235 parts we sell have a 60–80εm hot-dip galvanized layer on them, so they can be used outside for most jobs. ISO 1461 is the standard for hot-dip galvanized coatings on steel that has been made. Don't forget to put it on your order, and ask for thickness records that match. By itself, the wedge pin locks each joint in place. Check the pins every time you put something together and get rid of any that are broken, bent, or show a lot of wear. You shouldn't use the pin if it doesn't fit tightly into the rosette.
The scaffold standard in the US is 29 CFR 1926.451 and contractors must follow it. Four times the most weight that each scaffold and its parts were made to hold must be added to their own weight. Also, the scaffolding needs to be checked by a qualified person before each work shift. By following its rules, OSHA says that it keeps 4,500 people from getting hurt and 50 from dying every year. To keep people safe, it's also important to have training, inspections, and a design that has been approved. What does your area need? Talk to your engineer about it, and send us your project standard so we can share useful technical information.
Start by making sure you have a good plan, a trained team, and a solid base. Look for rust, cracks, corrosion, and welds that don't work right on every standard, ledger, brace, wedge, and base jack of disc lock scaffolding. Put in the base jacks first. Following that, put the standards, ledgers, transoms, and braces in place. Decks, handrails, toe boards, and access equipment are the last things that need to be added. Don't force parts that don't fit together to fit; instead, fully drive each wedge pin home. Before handing over, make sure the connection is secure, aligned, braced, and anchored. Check it again before each shift. This kind of steady sequence helps the crew move quickly and keeps the building straight.
Pick the right series for the job. Write down how much weight you expect, how high the scaffolding is, what the platform needs, how much weather it will be exposed to, how long the service will last, and how often you will put up and take down the scaffolding. Compare the coating, the weight, the tolerances, the type of material, the size of the tube and disk, and the holes that are made for connections. Look at samples or drawings to see if it will fit with parts that are already in your car. That way, your engineer and site manager can make sure they fit well before you place a big order. If you want to choose a supplier, don't just look at the unit price. Check out their quality control, past exports, paperwork, and packaging, as well as how much they can make.
Fleets that value standard parts, modular layouts, and connection points that are used over and over again can use this system. A lot of the people in this group work as contractors, rental companies, maintenance companies, or distributors. You might want to use a different system if the job has a lot of different tube angles, changes that aren't common, retrofit work, or an existing clamp-based inventory. They can work together if the engineer says it's okay. It is important to think about the load requirements, local laws, the environment, the skills of the supplier, the approval of samples, the delivery schedule, and the availability of spare parts. If you're not sure, send us your drawings. Our tech team will take a look at them.
To fill a bulk order of disc lock scaffolding, you need more than just the number of bays. Work levels, bracing, extra stock, tools, and storage space should all be included. Ask each supplier about the size, tolerances, coating, testing records, lead time, export documents, and grade of steel they offer. After that, you should look at the total landed cost, which includes freight, duties, inspection, storage, repairs, and the cost of replacement. A better product that can be used more times might be better than one that costs less per unit. How dense the packaging is can also change how much it costs to ship, so share your container plan early. Since Rizhao has its own harbor, it's easy for us to send things by sea.
We can process things according to your samples and drawings, and we can also make things the exact size you need. You send us drawings, we make sure the specs are correct and send you a sample. Your team then checks the fit and makes sure it meets the standards for inspection. Then, we check every detail again before we start making it. It finds mistakes in the specs early on, when they are still simple and inexpensive to fix. All the way through, our technical team tells you how to set things up and make them work together. Because our goods are sent to more than 100 countries, our export team makes shipping documents all the time.
It is a port city in Shandong called Rizhao. It has its own airport, seaport, and high-speed rail hub. This is the first place where Shandong Xingrui Building Materials Co., Ltd. opened in 2007. We have a 79,800-square-meter site with more than 40,000 square meters of standard workshops where 920 employees and 180 technicians work. We have 12 welding robots, 4 cold roll forming sets, 6 automatic welding lines, and 5 forging lines that are only partly automatic. Our products are CE-certified, and our management systems are ISO 9001, ISO 14001, and ISO 45001-approved. A skilled maker like us is in charge of the whole process, from the raw steel to the final check.
Disc lock scaffolding is ideally suited for heavy-duty construction due to its welded rosettes, wedge-pin locks, and standard parts. It is easy for crews to put together quickly and use again on other projects. You can get the Q235 steel system in 48mm and 60mm series. It has eight-hole rosettes that are 500mm apart and is hot-dip galvanized. Factory buildings, bridges, slab supports, and building fronts all use it. The safety of the scaffold depends on many things, such as the welds, the measurements, the coating, the bracing, the foundations, the approved designs, and the regular inspections that are needed by law, such as those required by OSHA.
When it comes to layouts that are done over and over, the system works faster than clamps and couplers. This is because clamps stay in place for details that don't happen very often. People who want to buy something should get samples to make sure the two work well together, compare the landed cost instead of just the unit price, and choose a supplier whose production can be tracked.
It holds up work on the outside of walls, slab formwork, bridge piers and decks, and maintenance work in factories that often involves a lot of heavy loads and many bays.
No, our series lists up to 30kN and 50kN of vertical capacity. However, the actual capacity depends on the design approval, the space between bays, the foundation, and the bracing.
Do not do it unless an engineer says it is okay. It's not always easy to tell if a rosette or wedge will fit, so ask for samples.
Send drawings, measurements, the amount of goods, the coating that will be used, the application, where the goods are going, and when they need to be delivered.
