مقياس ورقة SS

SS sheet gauge is a traditional but widely used system for defining stainless steel sheet thickness. It is especially common in fabrication and industrial design where quick identification is needed.

Key takeaways:

Gauge indicates thickness (higher number = thinner sheet)
18–20 gauge is most common for general stainless steel fabrication
Millimeter measurement is more precise and widely used in international trade
Gauge is mainly used for cold rolled stainless steel sheets

وصف

SS sheet gauge refers to the standardized system used to describe the thickness of stainless steel sheets (SS sheets). Unlike metric measurement (مم), gauge is an older industrial unit widely used in metal fabrication, تصنيع, and procurement.

The key point is:

Higher gauge number = thinner sheet
Lower gauge number = thicker sheet

لكن, gauge values are not perfectly linear and can vary slightly by standard system (US gauge is most commonly used in global stainless steel trade).

Gauge vs Metric Thickness (Key Difference)

Most international stainless steel production uses ملليمتر (مم) سماكة, while gauge is mainly used in:

North America
Some industrial fabrication sectors
Legacy engineering drawings

Conversion Relationship

Gauge is an approximate classification
mm is an exact measurement standard

على سبيل المثال:

16 gauge ≈ 1.52 مم
18 gauge ≈ 1.21 مم
20 gauge ≈ 0.91 مم

Why Gauge is Still Used in Stainless Steel Industry

1. Industry Tradition

Many fabrication shops and engineering drawings still specify gauge instead of millimeters.

2. Quick Identification

Gauge allows fast identification of sheet thickness without precise measurement.

3. Standard Fabrication Practices

Certain industries standardize materials by gauge for consistency in production.

Cold Rolled vs Hot Rolled in Gauge System

Gauge is mostly used for cold rolled stainless steel sheets, while hot rolled products are typically described in millimeters.

يكتب	Typical Thickness Representation
Cold Rolled SS Sheet	كَيّل (على سبيل المثال, 16 ga, 18 ga) or mm
Hot Rolled SS Plate	mm only (على سبيل المثال, 3 مم, 6 مم, 10 مم)
