Safety is a top priority for every enterprise. Keeping operators safe and free from accidents is the only way to guarantee our production capacity. In production, installing a machine guarding system is one of the most effective protective measures to protect the safety of operators.
Metan specializes in providing one-stop machine guarding system solutions. Of which, manufacturing standard compliance machine guarding systems is the most important link in our production. All our opening sizes and panel heights are set strictly in accordance with ISO 13857 & ISO 13854 standards.
You may identify your safety distance first and then choose the opening size of your machine guarding system.
According to ISO 13857, Sr represents regular openings for persons of 14 years of age and above.
The dimension of the opening, e, corresponds to the side of a square opening, the diameter of a round opening and the narrowest dimension of a slot opening.

Notes * If the length of the slot opening is 65 mm, the thumb will act as a stop and the safety distance can be reduced to 200 mm |
According to the safety distance required, you may choose as follows:
Safety Distance (mm) | Mesh Opening (mm) |
---|---|
120 | Slot opening 20 × 50, 20 × 100 |
Square opening 30 × 30 | |
200 | Square opening 40 × 40 |
800 | Square opening 50 × 50 |
