38" x 90" Grooved Tube

40x50 grooved tube

35x55 Grooved Tube

1. 38*90 Grooved Tube - **Spec Features** - **Dimensions**: This is a rectangular cross-section tube with a long side of 90mm and a short side of 38mm. Tubes of this size offer structural stability and are suitable for various applications requiring certain load-bearing capabilities. - **Groove Characteristics**: The grooved design adds more functionality to the tube. Grooves can be on the outer, inner, or both sides of the tube.

The outer groove typically measures 3-6mm in depth and 5-12mm in width, primarily used for installing accessories such as trim strips and hooks; the inner groove, if designed to conceal wiring, may be 4-8mm deep.

Width: 6 - 15mm, convenient for wire

Placement of cables, etc. - **Production Process** - **Molding Method**: Generally, the cold bending molding process is employed. The steel strip is passed through a series of designed rollers, gradually bending into the required rectangular shape.

Throughout this process, the spacing, pressure of the rolls, and feeding speed of the steel strip must be strictly controlled according to the 38*90 size requirements.

Typically, steel strips with a thickness of 1.5 - 3mm are used, which can be carbon structural steel or low-alloy steel. These materials exhibit good plasticity during the cold bending process, ensuring the quality of the pipe's forming. - **Welding and Groove Production**: After the pipe is formed, the edges of the steel strip are welded together using high-frequency welding. Once welding is complete, molds are used for stamping or CNC machining to create grooves.

The advantages of die stamping are high efficiency, suitable for mass production; CNC machining can achieve higher precision, used for situations with specific groove size requirements. - **Application Scenarios** - **Construction Field**: In the exterior decoration of buildings, it can be used as a frame for installing materials such as aluminum panels and stone facades. Grooves are used to secure hanging accessories, ensuring the firm installation of facade materials. In interior decoration, it can be used to make large display rack frames.

Grooves can be installed with partitions or display lighting to enhance the display effect. - **Industrial Equipment Field**: In the manufacturing of the outer shell frames of some large industrial equipment, 38*90 grooved tubes can provide stable structural support.

For example, in the frames of distribution panels and control cabinets, grooves are used to install side and door panel fasteners, facilitating equipment assembly and maintenance. 2. **40*50 Groove Tube** - **Specification Features** - **Dimensional Features**: The cross-section is rectangular, with the long side being 50mm and the short side being 40mm. This relatively smaller size offers advantages in spaces with high space utilization requirements, such as in small equipment or compact architectural structures. - **Groove Details**: The groove depth is approximately 2-5mm, and the width ranges from 3-10mm. For decorative purposes, these smaller grooves can be inlaid with colored plastic or metal strips to enhance aesthetics.

If used for functional installations, such as securing small parts, it can still meet basic requirements. - **Production Process** - **Molding Process**: We also use the cold bending molding process, but due to the smaller size, the requirements for molding are higher.

Typically, steel strips with thicknesses ranging from 1 to 2.5mm are used, materials such as Q235 carbon structural steel included. During the cold bending process, the forming parameters are controlled to ensure the accuracy of the tube's cross-sectional shape, with the angle deviations at the four corners kept within a very small range. - **Welding and Groove Machining**: Welding is generally done using high-frequency welding, with the welding parameters adjusted according to the thin-walled characteristics of the tube to avoid welding defects.

Groove machining can be achieved using small stamping dies, allowing for one-time stamping and ensuring precise groove dimensions and surface quality. - **Application Scenarios** - **Furniture Industry**: In the production of small furniture like coffee tables, bedside cabinets, etc., 40*50 grooved tubes can serve as frame materials. Grooves can be used for installing drawer slides, decorative strips, or for securing glass table tops, enhancing both the aesthetics and functionality of the furniture. - **Interior Decoration**: In the creation of small partitions and decorative screens within interiors, this type of tubing can act as a frame, with grooves used for installing decorative fabrics, wooden dividers, and so on, to create different spatial atmospheres. 3. **35*55 Grooved Tube** - **Specification Features** - **Size Specification**: The cross-section is rectangular, with the long side being 55mm and the short side being 35mm. This size of tubing is moderately sized, suitable for both small structures and applications requiring a certain degree of strength. - **Groove Features**: The groove depth is typically between 2-6mm, with a width ranging from 3-10mm. The grooves can be designed flexibly according to specific uses, such as setting grooves on the inside to conceal wires, or on the outside for installing hooks and other small components. - **Production Process** - **Forming Process**: Cold bending is the primary production method. Suitable steel strips (thickness generally 1-2mm) are bent into shape through roller bending. For the 35*55 size, the contour design of the rollers must match the target shape of the tubing.

During the bending process, attention must be paid to the uniformity of the steel strip's deformation, to avoid local excessive bending or creasing. - **Welding and Groove Production**: High-frequency welding is used for edge welding to ensure the sealability and overall strength of the tube. Groove production can be done by rolling or stamping processes, with rolling providing a smoother groove surface.

Stamping technology is more suitable for creating shapes with regular contours and specific dimensions. - **Application Scenarios** - **Automotive Interior Field**: In the manufacturing of car seat frames, 35*55 grooved tubes can serve as part of the supporting structure. Grooves can be used to install seat adjustment and heating devices, enhancing the comfort and functionality of the seat. - **Architectural Decoration Field**: They can be used in small decorative components of buildings, such as auxiliary supporting structures for window and door frames. Grooves are used for installing sealing strips, decorative lines, and more, enhancing the decorative and functional aspects of the building components.
