I. Coil pakhat rit zawng atana key parameters .
Coil pakhat rit zawng hi value fixed a ni lo va, a hnuaia parameter pali atanga chhut tur a ni:
1. Material density: Carbon steel pangngaiah chuan density 7.85 tons/cubic meter a awm a, stainless steel (304 ang chi) erawh chu ton 7.93 tons/cubic meter a ni thung.
2. Dimensions: 1.1.
- Thickness (mm): A tlangpuiin 0.5-20 mm a ni.
- A zau zawng (mm): A tam zawk chu 1000-2000 mm a ni.
- pawn lam diameter (mm): A tlangpuiin 800-2000 mm a ni.
- Inner diameter (mm): International standard chu 508 mm (20 inches) emaw 610 mm (24 inches) emaw a ni.
3. Chhiar dan tur formula:
$$weight (tons)=\\frac{π × (pawn lam diameter
4. Reference value te: 1.1.
- thin plate (1 mm thick × 1250 mm a zau): ton 3-5 vel a ni.
- Medium plate (10 mm thick × 1500 mm a zau): ton 15-20 vel a ni.
- Extra thick plate (20 mm thick × 2000 mm a zau): ton 25-30 thleng/roll thleng

II a ni. Practical factors hian weight a nghawng .
1. Thil siam chhuah dan inang lo: 1.1.
- hot-rolled coil hi cold aiin a rit zawk-rolled coil (10%-15% a rit zawk tan chuan 10%-15%) a ni.
- Japanese International Standard (JIS) coil-ah chuan a tlangpuiin inner diameter 610mm an hmang a, hei hi national standard nen a danglam hle.
2. Inkalpawhna leh dahkhawlna khapna:
- Coil pakhata kawngpui hmanga phurh chhuah chu a tlangpuiin ton 25 aia tam a ni lo (lirthei load limit a ni).
- Port lifting equipment-a load capacity sang ber chu a tlangpuiin coil khatah ton 30 a ni.
3. Industry lama thil tul bik:
- Galvanized coils chu automotive hmanna atan a ni: coil khatah ton 5-8 (automated production lines awm theihna tur a ngai)
- Color-Construction hmanna tur coated coils: ton 10-15 (transportation leh construction efficiency pahnih ngaihtuah).
iii a ni. User FAQs 1000 a ni.
1. Engtin nge quick estimate ka hmuh theih ang?
Formula awlsam: Ton khata rit ≈ 0.00617 x Thickness (mm) x A zau zawng (M) x Coil sei zawng (m)
Entirnan: coil 2mm a thuk, 1.5m a zau, leh 1000m a sei ≈ 18.5 tons a rit.
2. Engvangin nge specification inang coil te hian weight hrang hrang an rit?
- positive leh negative tolerances (eg, 3mm coil hi a takin 2.8-3.2mm a rit thei)
- Coil tightness hian pawn lam diameter-ah danglamna a thlen thin.
3. Engtin nge special materials te hi an chhut thin?
- Aluminum coil (density 2.7): A rit zawng chu steel coil volume inang chiah atanga 34% chauh a ni.
- Copper coil (density 8.9): steel coil aiin 13% zetin a rit zawk
