Gariiradda Birta Dahaarka leh ee PPGI/Midabka leh

1. Hordhac kooban

Xaashi bir ah oo hore loo rinjiyeeyay waxaa lagu dahaadhay lakab dabiici ah, kaas oo bixiya hanti ka hortagta daxalka iyo cimri dheer marka loo eego xaashiyaha birta galvanized.
Biraha salka u ah xaashida birta ee hore loo rinjiyeeyay waxay ka kooban yihiin kuwo qabow lagu duubay, HDG electro-galvanized iyo kuwo kulul lagu dahaadhay alu-zinc. Dahaarka dhammaadka ee xaashida birta ee hore loo rinjiyeeyay waxaa loo kala saari karaa kooxo sidan soo socota: polyester, polyester-yada silikoon ee wax laga beddelay, polyvinylidene fluoride, polyester-ka waara, iwm.
Habka wax soo saarku wuxuu ka soo baxay hal-dabool iyo hal-dubid ilaa laba-dabool iyo laba-dubid, iyo xitaa saddex-dabool iyo saddex-dubid.
Midabka xaashida birta ah ee hore loo rinjiyeeyay waxay leedahay xulasho aad u ballaaran, sida oranji, midab kareem ah, buluug cirka madow, buluug badda, casaan dhalaalaya, casaan leben ah, caddaan foolmaroodi ah, buluug porcelain ah, iwm.
Xaashiyaha birta ah ee hore loo rinjiyeeyay waxaa sidoo kale loo kala saari karaa kooxo iyadoo loo eegayo qaab-dhismeedkooda dusha sare, sida xaashida caadiga ah ee hore loo rinjiyeeyay, xaashida la daabacay iyo xaashida daabacan.
Xaashiyaha birta ah ee hore loo rinjiyeeyay waxaa inta badan loo bixiyaa ujeedooyin ganacsi oo kala duwan oo daboolaya dhismaha dhismaha, qalabka korontada guryaha, gaadiidka, iwm.

2. Nooca qaab-dhismeedka dahaarka
2/1: Laba jeer ku dahaadho dusha sare ee xaashida birta ah, hal mar ku dahaadho dusha hoose, laba jeerna ku dub xaashida.
2/1M: Laba jeer ku dahaadho oo dub labada dusha sare iyo kuwa hooseba.
2/2: Laba jeer ku dahaadho dusha sare/hoose oo laba jeer dub.

3. Isticmaalka qaababka kala duwan ee dahaarka
3/1: Astaamaha ka hortagga daxalka iyo iska caabbinta xoqidda ee dahaarka dambe ee lakabka keliya ah waa kuwo liita, si kastaba ha ahaatee, sifooyinka dhejiska ayaa wanaagsan. Xaashida birta ah ee hore loo rinjiyeeyay ee noocan ah waxaa inta badan loo isticmaalaa guddiga sandwich-ka.
3/2M: Dahaarka dambe wuxuu leeyahay iska caabin daxaleed oo wanaagsan, iska caabin xoqid iyo waxqabad wax lagu qurxiyo. Intaa waxaa dheer, wuxuu leeyahay dhejis wanaagsan wuxuuna ku habboon yahay guddi lakab keliya ah iyo xaashida sandwich.
3/3: Astaamaha ka hortagga daxalka, iska caabbinta xoqidda iyo habka farsamaynta ee dahaarka dambe ee xaashida birta ah ee hore loo rinjiyeeyay ayaa ka wanaagsan, sidaa darteed si weyn ayaa loogu isticmaalaa sameynta duubka. Laakiin sifooyinka dhejiska ah waa kuwo liita, sidaa darteed looma isticmaalo guddiyada sandwich-ka.
