Start Sheet Metal Assembly at HULK METAL
HULK Metal assembles sheet metal parts on dedicated riveting and threaded-fastening lines, with a defined assembly process and an inspection step before packing. A quotation follows the reading of your assembly drawing: the material grade and sheet thickness, the joining method the joint needs, the accuracy the assembly has to hold, the number of pieces, and the surface treatment or packaging you expect afterwards. Kindly contact us if you have an assembly order and need OEM production; our sales manager will take you through the factory on-site or online.

Process of Our Sheet Metal Assembly Service
We've sorted out how to provide quality sheet metal assembly services to our customers. When we choose a factory, we can also fully understand their production process to determine their professional capabilities. You can use our introduction as a comparison.
Assembly is where defects are easy to hide, so we check it at three points. Before parts reach the line, incoming parts are verified against the drawing - hole positions, whether threads are already tapped, and material condition; raw material tolerance is held to ±0.05 mm and finished part size to ±2 mm. During assembly, operators confirm that rivets are fully set, that threaded fasteners are tightened to the drawing requirement, and that welded joints are visually sound. Before packing, the finished assembly goes through a dimensional check and a coating inspection, and where corrosion resistance matters, coating thickness and salt spray testing are added. The quality control center runs CMM, hardness testers, metallographic microscopes, spectrometers and salt spray chambers.

01
Get Drawings And Requirements
You need to send at least one 2D drawing and tell us some information you know, such as quantity, acceptable delivery methods, and some requirements not mentioned in the drawings, such as surface treatment method, packaging method, etc. Of course, our sales team will provide you with more suggestions during communication.
-
02
Custom Solutions
We will use your needs obtained through in-depth communication to improve all aspects of the solution. Your order will be completed strictly according to the solution. Any problems that arise will have effective and appropriate solutions.
-
03
Welding Samples Sending & Testing
After the solution is determined, we will complete the cutting, stamping, and other processes of sheet metal parts according to the process and complete quality inspection. We will send samples to you to compare the test data. After passing the inspection, we will arrange the details of the production and start manufacturing.
-
04
Order Scheduling
Based on the delivery date, order size, and other information, we will purchase raw materials in advance, arrange the production site, and replace molds so that we can complete the order more efficiently and with guaranteed quality and quantity.
-
05
Raw Materials Purchasing & Testing
The purchased raw materials need to undergo strict physical and chemical property testing first. Only raw materials that pass the inspection will be used for the production of orders. We will issue a product inspection report for each batch of products.
-
06
Raw Materials Cutting
We will use laser cutting to complete the pre-processing of raw materials to facilitate the stamping and forming process. In most cases, we use laser cutting because it can save more material and labor costs.
-
07
Sheet Metal Stamping
According to the structural characteristics of sheet metal parts, we need to use punching, bending, spinning, and other processes to complete the further processing of the cut raw materials.
-
08
Sheet Metal Welding
The stamped sheet metal parts are pre-assembled through the welding process. Surface treatment of the whole after welding can make the surface coating continuous and more uniform. Performance in all aspects will be even better.
-
09
Surface Treatment
Surface treatment needs to be selected according to the material of the sheet metal part and the specific usage scenario. The surface treatment services we can provide include galvanizing, electrophoresis, passivation, anodizing, polishing, wire drawing, etc. You can contact us to learn more.

010
Assembly
The surface-treated sheet metal parts need to be assembled to complete the final step. We have fully automatic screw machines, efficient riveting machines, and experienced operators to complete product assembly faster.
-
011
Warehousing & Delivery
We have a strictly managed warehousing center that can provide free temporary storage services for goods. Our logistics team can complete loading, transportation, port entry, and more faster. Realize seamless connection from factory to port, station, and air freight station. The professional freight consulting team can help you find a more suitable freight company to complete the final handover of goods.

012
After Service
We will be responsible for the quality of the goods you receive. We have a complete team to provide one-to-one service to develop solutions that satisfy you based on the problem.
Sheet Metal Assembly Service Types We Can Supply
Two non-welding assembly routes do most of the work on sheet metal parts: riveting and threaded fastening. Riveting is permanent - the parts are prepared with rivet holes, solid rivets are pressed into the joint, and the assembly comes apart only by destroying the rivets, so it suits a part that stays together for its whole service life. Threaded fastening is removable - either the thread is tapped into the sheet metal part itself, or a plain hole is used with a screw and nut. The drawing decides which: threaded holes are called out on it, and if they are not, we do not add them on the shop floor. The choice is usually settled by what happens after the part leaves the factory - equipment that will be serviced, repaired or upgraded in the field wants screws, while a joint that only has to hold is cheaper and stiffer riveted. On inspection, riveted joints are checked for fully set rivets and hole edge condition, threaded joints for thread engagement and tightness against the drawing, and both against the assembly dimensions before packing.

Sheet Metal Assembly Introduction
We've put together some information on sheet metal assembly. This can help you better understand what process your foundry uses to complete your order. You can learn and communicate with them at the same time.
-
Assembly
Sheet metal assembly services refer to the process in which sheet metal manufacturers equipped with assembly lines use riveting, welding, thread fastening, adhesive bonding, and crimping seams to complete the assembly of sheet metal parts. We need to choose the appropriate link method based on the performance requirements of the sheet metal parts in the usage scenario and the ease of transportation of the finished product.

Welding, Riveting, Screw Fasteners Link Comparison
Welding, riveting, and screw fastener links can all be used as a means of assembly in the metal fabrication process. Welding and riveting is a permanent process. After welding is completed, it can only be cut and separated. If not handled properly, the structure of the sheet metal parts will be damaged. It is more suitable for structures that will not easily change the shape. Linked locations can be unlinked and linked again using special tools. Riveted sheet metal parts have excellent shear resistance but weak tensile properties. Threaded fasteners are flexible links with relatively balanced shear and tension forces and are suitable for most environments.
From a convenience perspective, only threaded connections can be disassembled and reused at any time, while riveting and welding are one-time connections, and fasteners cannot be reused after installation.
From a complete point of view, threaded connections are the best, riveting is second, and welding is last.
From the perspective of quality control, threaded connections are more convenient and suitable for quality inspection and inspection at any time, followed by welding and riveting.
In terms of cost of use, the opposite is true. The cost of welding is relatively low, the cost of riveting is slightly higher, and the cost of threaded connection is the highest among the three connection methods.
In terms of lightweight construction, riveting is the lightest, followed by welding, and threaded connections are the highest.
Therefore, among these three methods, there is no way to compare which one is better. We can only say which one is more suitable for the installation environment.
When you choose HULK Metal as your sheet metal fabricator, you can enjoy faster delivery and lower prices. Let our engineers develop a more suitable solution for you.
