Tiirarka dhismaha iyo tiirarka ayaa lagu dabaqay dhismayaal dabaqyo badan ah, dhismayaal warshadeed, bakhaarro, buundooyin iyo in ka badan si ay ugu adeegaan taageerada koowaad ee qaadista.
BiriijkaIsticmaalka I-beams sida alwaaxyada hoose ama sare ee buundooyinka si loo taageero gaadiidka iyo socodka dadka lugeynaya.
Taageerada Mashiinada Culus:Mashiinnada wax soo saarka waaweyn iyo dhismayaasha birta dhufto ee. Dib-u-habaynta qaab-dhismeedka - hagaajinta, xoojinta ama dayactirka dhismo jira, si loo kordhiyo caabbinta foorarsiga iyo awoodda wax-soo-saarka.

Xoojinta Dhismaha
1) Xafiiska Laanta - Taageerada Isbaanishka ku hadasha, Kaalmada fasaxida kastamka, iwm.
2) In ka badan 5,000 oo tan oo kayd ah, oo leh cabbirro kala duwan
3) Waxaa soo kormeeray hay'ado awood leh sida CCIC, SGS, BV, iyo TUV, oo wata baakadaha caadiga ah ee badda.
Ilaalinta iyo Baakaynta DhamaystiranXidhmo kasta oo I-beam ah waxa lagu duuduubay taarpaulin, oo lagu xoojiyay daboolka kulaylka-xidhan ee roobka, oo ay ku jiraan baakado qallajiye ah oo lagu xannibo qoyaanka.
Isku xidhka SuganXidhmooyinku waxay ku xidhan yihiin 12-16 mm bir ah oo loo dhisay si ay u qabtaan shuruudaha kor u qaadida dekeda ee Maraykanka, taageeraya 2-3 tan xidhmo kasta.
Nadiifi calaamadaynta u hoggaansanaantaXirmado kastaa waxa ay sitaa summada Ingiriisiga iyo Isbaanishka oo tafaasiilinaya darajada, cabbirka, koodhka HS, lambarka dufcadda, iyo tixraaca warbixinta imtixaanka.
Maareynta Qaybta La Weyn:I-beams 800 mm iyo wixii ka sareeya waxay helayaan dahaarka saliida ka hortagga miridhku ka samaysan ee warshadaha ka hor inta aan la duubin tapaulin si loo kordhiyo ilaalinta.
Saadka la isku halayn karo: Iskaashi xooggan oo lala yeesho MSK, MSC, iyo COSCO waxay xaqiijiyaan jadwal xasilloon iyo gaarsiin la isku halleyn karo.
Xaqiijinta Tayada:Nidaamyada oo dhan waxay raacaan heerarka ISO 9001, iyagoo dammaanad qaadaya in I-beam kasta uu ku gaaro goobta xaalad aad u wanaagsan oo diyaar u ah fulinta mashruuc hufan.
S: Waa maxay halbeegyada birtaada birta ah ee u hoggaansama suuqyada Bartamaha Ameerika?
A: Badeecadahayadu waxay la kulmaan ASTM A36, A572 Heerarka Fasalka 50, kuwaas oo si weyn looga aqbalo Bartamaha Ameerika. Waxaan sidoo kale bixin karnaa alaabooyin u hoggaansamaya heerarka maxalliga ah sida NOM ee Mexico.
S: Intee in le'eg ayay tahay wakhtiga keenista Panama?
J: Xamuulka badda ee ka imanaya Dekadda Tianjin ilaa Aagga Ganacsiga Xorta ah ee Colon wuxuu qaadanayaa 28-32 maalmood, wadarta wakhtiga gaarsiinta (oo ay ku jiraan wax soo saarka iyo kastamku) waa 45-60 maalmood. Waxaan sidoo kale bixinaa xulashooyinka rarida degdega ah.
S: Ma bixisaa kaalmada fasaxa kastamka?
J: Haa, waxaanu la shaqaynaa dilaaliinta cashuuraha ee badhtamaha Ameerika si aanu uga caawino macaamiisha inay qabtaan ku dhawaaqida kastamka, bixinta cashuuraha iyo habraacyada kale, anagoo hubinayna in si habsami leh loo gaadhsiiyo.
