When selecting a floor spring, it is important to evaluate door width, door weight, opening direction, hold-open requirement, installation space, and door type. For glass doors, double doors, offset doors, fire-rated doors, or heavy entrance systems, buyers should compare load capacity, opening angle, top pivot compatibility, cement case size, and maintenance convenience.
- Choose the proper floor spring model based on door width and door weight.
- Confirm the opening direction and installation conditions before selection.
- For high-traffic commercial entrances, prioritize durability and load capacity.
- If future maintenance is important, an exchangeable floor spring may be a better choice.
- For special projects or heavy doors, consult a professional floor spring manufacturer for evaluation.
Floor Spring Model Comparison & Application Suggestions
Different floor spring models are suitable for different door conditions. For standard commercial doors, common glass doors, and typical single or double door installations, S200 and S220 are good starting points. If you need more flexible spindle extension options, replacement convenience, or different floor conditions, Exchangeable S200 and Exchangeable S221 may be more suitable. For narrow spaces, high-load doors, or oversized entrance systems, S275 and S280 are recommended.
