덕트 두께 별 표기 및 중량 정보 입니다. 아연도금 강판 Gauge 에 따른 Nominal,Minimum 두께 (Thickness) 테이블 입니다. 

Galvanised Sheet Thickness
Thickness, mm			Nominal Mass
Gauge	Nominal		Minimum	kg/m2
30	0.399		0.319	3.20
28	0.475		0.395	3.81
26	0.551		0.471	4.42
24	0.701		0.601	5.64
22	0.853		0.753	6.86
20	1.006		0.906	8.08
18	1.311		1.181	10.52
16	1.613		1.463	12.96
14	1.994		1.784	16.01
13	2.372		2.162	19.07
12	2.753		2.523	22.12
11	3.132		2.902	25.16
10	3.510		3.280	28.21
Notes:
1. Minimum thickness is based on thickness tolerances of hot-dip galvanised sheets in cut length and coils (per ASTM standard A525-80). Tolerance is valid for 1220 and 1520-mm wide sheets.
2. Galvanised sheet gauge is used for convenience. A metric series would conform to ANSI Standard B32.3, and the tolerances in ASTM Standard A5225M apply.
Uncoated Steel Sheet Thickness
Thickness, mm			Nominal
Minimum		Mass
Gauge	Nominal	Hot-Rolled	Cold-Rolled	kg/m2
28	0.378	0.328	3.05
26	0.455	0.405	3.66
24	0.667	0.587	4.88
22	0.759	0.679	6.10
20	0.912	0.832	7.32
18	1.214	1.084	1.114	9.76
16	1.519	1.369	1.389	12.20
14	1.897	1.717	1.767	15.25
13	2.278	2.101	2.456	18.31
12	2.656	2.456	2.506	21.35
11	3.038	2.838	2.888	24.40
10	3.416	3.216	3.266	27.45
Notes:
1. Minimum thickness is based on thickness tolerances of hot-rolled and cold-rolled sheets in cut length and coils (per ASTM Standards A366, A568, and A569).
2. Table is based on 1220-mm width coil and sheet stock. 1520-mm coil has same tolerance, except that 16 gauge is +/- 0.18-mm in hot-rolled coils and sheets
3. Manufacturer's standard gauge is used for convenience. A metric series would conform to ANSI Standard B32.3, and the tolerances in ASTM Standard A568M apply
