Dve glavni značilnosti rastlinjakov z več razponami sta preprosta struktura in prilagodljiva oblika . Preprost večkratni rastlinjak z več membrani je zasnovan tako, da odstrani nekatere strukture več membranskega rastlinjaka in je v glavnem primerna za grozdne zelenjave, gojenje jagod, gojenje sadik obrobe itd. Struktura rastlinjakov z več razponi je treba redno vzdrževati . Pokrivalo gradivo bi moralo doseči namen dobre osvetlitve in izolacije . Zato je treba, če so potrebni okrepljeni ukrepi, uhajanje popraviti pravočasno .
The two major advantages of multi span film greenhouses are: (1) simple structure: due to the characteristics of the covering material, the load-bearing structure, film fixing system, and installation requirements of plastic greenhouses are relatively simple. The load-bearing structure adopts hot-dip galvanized light steel or ordinary steel structure, generally using hot-dip galvanized light steel structure. Steel structure je boljši v montažni strukturi . Glavni jekleni okvir rastlinjaka je sestavljen predvsem iz stolpcev, obodnih žarkov, zgornjih lokov, zgornjih palic, križcev, ohlapnih nosilcev, žlebov itd. when the greenhouse is covered with materials and the roof is not mechanically connected, the roof only bears gravity loads and positive wind pressure, and the wind pressure is transmitted to the gutter and columns, greatly optimizing the stress of the greenhouse structure.(2) Flexible and diverse dimensions: Due to the structural characteristics of connected greenhouses, the development of large-span connected film greenhouses has been influenced by various factors such as regional and customer demands. Countries around the world have launched production and promotion based on plastic greenhouses. Their respective standards have resulted in a large number of different forms and specifications of plastic film multi span greenhouses, such as high arched greenhouses with different spans, double arched greenhouses, serrated greenhouses, small arched multi span greenhouses, ETC . Zato je še vedno težko povzeti in opisovati dimenzije posameznih plastičnih rastlinjakov . Zato je mogoče razpon in odprt prostor fleksibilno oblikovati v skladu
