Thickness 3-60mm, dav 10-150mm, duab plaub hla ntu tiaj tiaj steel.
1. Kev tshwm sim
Curvature rooj
| Qib raug | Curvature (mm) tsis ntau tshaj | |
| Curvature ib 'meter' | Tag nrho curvature | |
| Qib qub | 4 | 0.4% ntawm kev xa khoom ntev |
| Qib siab dua | 2.5 | 0.25% ntawm kev xa khoom ntev |
2. Cov duab sib tshooj
Hla-sectional puab rooj
| Thickness (hli) | Qhov siab tshaj plaws qhov ntev (C tus nqi) (mm) |
| Tsawg dua los yog sib npaug li 5 | 1 |
| >5-10 | 20% ntawm thickness |
| >10 | 15% ntawm thickness, tus nqi siab tshaj yog 3.5 |
3. Nyhav
(1) Feem ntau, qhov ntev ntawm cov hlau tiaj tus yog xa los ntawm qhov hnyav tiag tiag. Nws tuaj yeem xa los ntawm qhov ntsuas qhov hnyav tom qab kev pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom thiab tau teev tseg hauv daim ntawv cog lus.
(2) Pav ca steel yog xa raws li cov kab ncaj nraim.
