Dunida qalabka dhismaha ee waxqabadka sare leh, usha gudbinta (sidoo kale loo yaqaan tor "drive bar") waa mishiinka aan la arki karin ee awood u leh nidaamyada qufulka badan. Wax-soo-saareyaasha iyo qaybiyeyaasha, xisaabinta dhererka saxda ah ee ulahan ayaa muhiim ah. Qiyaasta khaldan waxay keentaa xidhidh xumo, hawlgal adag, ama fashilka dhammaystiran ee isku xigxiga xidhitaanka.

1. Fahamka isbeddellada

Kahor intaadan samayn xisaabinta, waa inaad aqoonsataa saddex cabbir oo muhiim ah oo ku dhex jira nidaamka astaantaada:

• Sash Height (H): Wadarta dhererka toosan ee daaqada ama saqafka albaabka.
• Dhererka Gacanta (h): Masaafada u jirta gunta gunta ilaa dhexda dunta gacanta.
• Hardware Groove (C-Groove ama U-Groove): Kanaalka gaarka ah ee ay usha ku nooshahay, kaas oo go'aamiya dhabarka dambe ee gudbinta.

2. Qaanuunka Xisaabinta Aasaasiga ah

Caadi ahaan, ulaha gudbinta ayaa loo qaybiyaa qayb sare iyo qayb hoose oo ka soo jeeda booska gacanta. Si loo oggolaado wadista geesaha iyo nadiifinta, wax-soo-saarayaashu waxay adeegsadaan macquulka soo socda:

3. Go'aaminta Goobaha Qufulka

Doorashada dhererka usha waa kala bar dagaalka; meelaynta "likaha" ama kamaradaha qufulka ayaa ah waxa xaqiijinaya amniga.

• Sash Gaaban (Ka hooseeya 800mm): Caadiyan waxay u baahan tahay 2 dhibcood oo quful dhinaca toosan ah.
• Saxanka caadiga ah (800mm - 1600mm): Wuxuu u baahan yahay 2 dhibcood oo quful oo loo qaybiyo si siman.
• Albaabada Ammaanka Sare (In ka badan 2000mm): Waxa laga yaabaa inay u baahdaan 4 dhibcood ama in ka badan oo lagu xidho oo ay weheliyaan dariiqyada geesaha sare iyo hoose.

Talooyin Ilaha Khabiir

Markaad raadinayso ulaha gudbinta ee mashaariicda waaweyn, had iyo jeer codso warbixinta waafaqsanaanta farsamada . Maadaama aluminium profiles kala duwan yihiin by extruder, masaafada u dhaxaysa xarunta gacanta iyo jeexdin hardware (backset) waa in si fiican u waafaqsan yahay sanduuqa gudbinta. Birta 304 ee birta ah iyo aluminiumka aluminiumka ah ayaa loo aqoonsan yahay agabka heerka warshadaha ee profiles bar, oo loogu talagalay in laga hortago daxalka korantada ee gudaha kanaalada astaanta aluminium.
