Itsindaigufwa ry'umutakayerekeza ku gitereko cyo gushyigikira umutaka, igufwa ry’umutaka ryabanje rigizwe ahanini n’ibiti, igufwa ry’umutaka rya bamboo, hanyuma hariho igufwa ry’icyuma, igufwa ry’icyuma, igufwa rya aluminiyumu (rizwi kandi nka Fiber bone), igufwa ry’amashanyarazi n’igufwa rya resin, ahanini bigaragara mu buryo bw’igufwa rigabanuka, rifite imiterere yo gutwara urumuri kandi rworoshye.
Igufwa ry'icyuma ni ryo rikomeye kandi riramba cyane, ntiryoroshye kurivuna, rimara igihe kirekire. Igufwa ry'icyuma rirakomeye kandi ntiryoroshye kurivuna, rirahangana neza n'umuyaga, ryoroshye kuringiza uko igihe kigenda gihita. Igufwa rya aluminiyumu ripima umucyo kandi igiciro ni gito. Ubushobozi bw'igufwa rya fibre ya shimi, riraramba, rirahangana n'umuyaga rirakomeye. Ubushobozi bw'igufwa rya fibre ya karuboni, rirahangana n'umuyaga muri rusange, igiciro ni cyo kinini kurusha ibindi bikoresho byose. Igufwa ry'amashanyarazi n'igufwa rya resin byoroshye kandi biratwara.
Ingorane ni uko byoroshye kuzipfunyika kandi ntizishobora kwihanganira umuyaga cyane.
Ese ni byiza kugira amagufwa menshi mu mutaka?
Umubare w'amagufwa ntabwo uhoraho, ariko uhindurwa hakurikijwe ibyo akeneye bitandukanye, nta shingiro rihari niba menshi cyangwa make ari meza kurushaho.
Ku bwiza bw'umutaka ntibiterwa gusa n'umubare w'amagufwa, ahubwo biterwa n'ibikoresho bikoreshwa mu gukora.
Amagufwa angahe y'umutaka adashobora kumenya neza umutaka mwiza cyangwa mubi, ariko uko umubare w'amagufwa y'umutaka urushaho kuba mwinshi, uko umutaka uba mwinshi, ni ko amagufwa y'umutaka aba meza, ni ko umubare w'imizi uba ukomeye, imizi iba myinshi, ariko kandi iremereye. Igikanka cyuzuye muri rusange ni 6-8, amagufwa menshi ashobora kugera kuri 24, ahanini akoreshwa mu giti kigororotse cy'amagufwa abiri yuzuye.
Igicucu cy'izuba muri rusange gifite imizi 6, imizi 8 ahanini, dukunze kubona amagufwa 8 y'icyuma n'amagufwa y'icyuma. Amagufwa 8 y'amagufwa 16 mu mwuzure ibiri n'amagufwa abiri y'izuba yakoreshejwe cyane, ariko
Kugira ngo tugabanye ikiguzi ubu hari imitaka ibiri isobanutse neza ifite amagufwa 7 yo gukora. Amagufwa 6 n'amagufwa 7 mu gicucu cy'umutaka ugaragara cyane bikoreshwa cyane, ibikoresho ahanini birimo igufwa rya aluminiyumu (fiber bone) resin bone.
Hanyuma, igiciro cy'igufwa rya resin kiri hejuru cyane, bityo gikunze gukoreshwa mu myenda y'igiciro cyo hejuru. Imyenda y'igiciro cyo hejuru yita ku buryo iteye, kandi izareba imiterere y'imyenda y'icyuma mu gihe cyo gushushanya imyenda y'icyuma.
