Spiral staircases ni hta lahkam galu ai gaw 80 cm hta n yawm ging ai.
Lapran daw hta step a galu kaba ai lam gaw n yawm htum 20-25 cm rai ra ai, galu dik ai daw hta - 40 cm hta n jan ra ai. Spiral staircase a lahkam ni a tsaw ai gaw, hkawm sa na matu hpaji jaw da ai tsaw ai hta grau kaba na re. Marching stairs a matu step ni a tsaw de 16 cm, spiral stairs a matu - 18 cm rai nga ai.
Lagaw n-gun rawng ai shara hta, shingnip n-gun rawng ai n-gun gaw 25-30 cm daram, n-gup magap hku - n yawm htum 30-35 cm rai ra ai. Ndai step depth gaw grai shim lum na re.
