Rectangular Duct Fabrication

JOYEAR's rectangular duct fabrication adopts the German industrial standard system and achieves breakthrough control in precision molding technology. The flatness tolerance of the duct surface is strictly controlled within 1 mm per meter, and professional instrument testing and visual double verification are used to ensure that there are no visible bumps or deformations. All external angle steel reinforcement structures are designed according to standardization, with a maximum spacing of no more than 1.5 meters. This enhanced support solution reduces the deformation of the air duct by 65% under 500 Pa negative pressure conditions.

In the manufacturing process, an advanced CNC plasma cutting system is used, with a cutting tolerance of ±0.3 mm, which is equivalent to the diameter of a human hair. In the bending process, strict adherence to R angle control standards is maintained, with the bending radius not exceeding 1.5 times the plate thickness. This technology effectively prevents micro-cracks caused by stress concentration while ensuring smooth airflow.

By integrating German standards and digital manufacturing technology, we have achieved a breakthrough in the bite accuracy of 0.3 mm for duct joints. This precision manufacturing system reduces the air leakage rate to less than 8%, and with the zinc-chromium coating treatment of the incision anti-corrosion process, the system life is increased by 20% compared with conventional products. Each production link undergoes three dimensional re-inspections to ensure that the final product meets industrial-grade sealing requirements.

JOYEAR functions as a privately owned family business founded in 2008, focusing on providing large-scale, efficient industrial part export services to global customers. JOYEAR provides precision metal manufacturing solutions. Submit your technical drawings or digital models, and our skilled engineers will transform them into physical components.

Our material inventory includes: carbon steels, mild steels, structural-grade steels, corrosion-resistant steels, aluminum alloys, and copper alloys. Available stock forms consist of: plate material, bar material, tubular sections, round stock, strip material, and block material.

Our product range includes:

Materials: Carbon steel / Mild steel / Structural steel / Stainless steel / Aluminum / Copper, etc.

Forms: Sheets / Profiles / Tubes / Round bars / Flat bars / Square bars, etc.

During production, we utilize a dual-mode laser and plasma cutting system to lock tolerances at ±0.3 millimeters, combined with a fully automated zinc-chromium coating edge corrosion protection process, eliminating rust risks from the source.We ensure each product meets industrial-grade sealing requirements through a three-tier quality inspection process, helping customers reduce operational costs by 25%.

► Luxury Residential Fresh Air Systems

---

Rectangular ducts are the preferred choice for high-end residential ventilation systems due to their unmatched space utilization and noise reduction performance.

 

Laser cutting with a tolerance of ±0.3mm ensures zero gaps in the joints, eliminating the risk of carbon dioxide accumulation.

 

Zinc-chromium coated joints combined with food-grade seals deliver fresh oxygen as pure as a forest, increasing deep sleep time by 37%.

► Commercial Kitchen Exhaust

---

Kitchens generate a lot of grease fumes and space is limited. Rectangular ducts can be installed close to walls or ceilings, saving space.

 

They have tight joints, minimal air leakage, and high exhaust efficiency.

 

They are easy to disassemble for cleaning, require little maintenance, and can be flexibly adjusted in size according to the size of the kitchen, making them extremely practical.
