Issiq prokatlangan H nurlari va I nurlariga umumiy nuqtai nazar
H shaklidagi kesimli issiq prokatlangan po'lat nur, asosan qoziq va ushlab turuvchi konstruksiyalarda ishlatiladi. H-nur I-nurdan ishlab chiqilgan va optimallashtirilgan, bu esa yaxshiroq mexanik imkoniyatlarga ega bo'lgan tejamkor profilli po'lat turidir. To'r plitalari va gardishlar vertikal chiziqda joylashgan. Ichki gardish tashqi gardish bilan parallel ravishda joylashgan. Uning gardishlari juda tekis va qirralari aniq, ayniqsa kesma shakli va "H" harfi o'rtasidagi o'xshashlik tufayli shunday nomlangan.
Po'latdan yasalgan I-nurlar turli xil konstruktiv qo'llanmalar uchun ishlatiladi. I-nurlarning xususiyatlari va xususiyatlarini tavsiflash uchun maxsus terminologiya qo'llaniladi.
Po'latdan yasalgan I-nurlarni osmono'par binolar va magistral yo'llardan tortib, turar-joy qurilishi va sanoat kranlarigacha deyarli barcha qurilish loyihalarida topish mumkin. I-nurning xususiyatlari uni nur kuchi va og'irligini muvozanatlash uchun optimal tanlovga aylantiradi. I-nurning ko'ndalang kesimining katta qismi nurning neytral o'qidan uzoqda joylashgan bo'lib, natijada yuqori inersiya momenti yoki "I" qiymati hosil bo'ladi.
