Apex Steel Catalogue

COLD FORMED SECTIONSAccurately sized strips, cut from high quality hot rolled mild steel coils, are fed into the

tube mill. The flat strip is gradually formed to a round profile with an open seam along its length.

A high frequency induction welding technique is used to form a strong continuous seam joint. The formed pipe passes through and external bead scarfing and sizing process to bring its dimensions

within specified tolerances. The pipes are then cut to desired length.

The cut pipes are end faced, straightened and hydro tested. Each pipe is subjected to a specified pressure at the hydrotester to ensure that welding is strong and free from leakage.

After this stage, if required, the pipes are galvanised threaded and socketed. The manufacturing process uses Hot Rolled (HR) mild steel with a composition of carbon 0.20% maximum : phosphorous 0.05% maximum : manganese 1.20%

maximum; sulphur 0.05% maximum and silicon traces.

All the water pipes are threaded to (BSPT specifictaion and are fitted with a socket on one end).

Cold-formed steel sections commonly known as hollow sections conform to Kenya Bureau of Standards KS 02-104. Hollow sections are manufactured on tube mills using high frequency induction welding technique. The strip is continuously seam welded while round in shape and then gradually brought to the desired section in the sizing mill. The welded seam is put to a great amount of cold working while being sized. This is a very severe test of the strength of a seam weld and ensures that each length of hollow section is welded for maximum strength.

Steel Door Frame sections are cold formed using hot rolled steel strips, During roiling, care is taken to ensure dimensional uniformity, extremely smooth surface finish and accurately finished edges. The section, being of structural strength has pf late come to be a better alternative to timber door frames.

Timber Door Frame section have been having problems like deterioration due to weather, warping and difficult of installation, White Ants etc.
