YunDe has the widest range of expanded metal products in the industry.
Expanded metal is an extremely versatile material. It is available in a wide variety of ferrous and non-ferrous metals, as well as a wide range of mesh sizes.
Although there are standard designs, what makes our process so versatile is the pattern variations you can choose from. These patterns can be specified to achieve whatever characteristics are most critical for your specific applications.
When selecting expanded metals, there are many considerations to keep in mind. For instance, increased pattern size alters the open area and improves cost-effectiveness, while varied strand width changes both the appearance and weight.
Expanded metal converts solid sheet or plate metals into a material with diamond-shaped openings joined by continuous, uniform strands. The simultaneous slitting and stretching process generates an expanded material with essentially no scrap. The result is a strong, structurally sound, no-raveling metal product that permits the passage of heat, fluids, light, sound, and air.
Although there are standard designs, expanded metal is almost infinitely variable in pattern and can be specified to achieve whatever characteristics are most critical.
These are the advantages that set expanded metal apart from either perforated metal or wire cloth, making it both more economical and easier to handle.
Step 1. Sheet or plate is advanced beyond the face of the bottom die in an amount equal to the strand width before flattening. The sheets are then fed into an expanding machine.
Step 2. The top die then descends and simultaneously slits and cold forms an entire row of half diamonds.
Step 3. The top die then ascends and moves one half of a diamond to the right as the base sheet or plate moves forward one strand width.
Step 4. The top die descends, slits and forms another full row of half-diamonds completing a row of full diamonds in two strokes.
Step 5. The die then ascends and returns to its initial position.
