About Our Bolt Division

Trusted Sag Rod Manufacturer & Supplier in India

E S Haji & Co. is a trusted manufacturer of Sag Rods in India, supplying Z sag rods and threaded sag rods that support and align purlins and girts in pre-engineered and industrial buildings since 1994. Sag rods carry the lateral load of roof and wall sheeting, keeping purlins straight and preventing sag, twist and deflection between main frames during erection and in service.

Threaded steel rods installed between purlins and girts, sag rods run perpendicular to the purlin line — tying members together and transferring load up to the rafter or eave, keeping everything aligned. Z sag rods are bent to pass neatly through the purlin web, making installation fast and the connection clean in Z and C purlin systems.

Each sag rod is produced to your purlin spacing with the correct diameter, thread and length — in mild steel, galvanised or stainless finish. Available in single lengths up to 12 metres on request, with Mill Test Certificates and reliable PAN India delivery.

Client Testimonials

What Our Clients Say

★★★★★

We sourced Z sag rods from E S Haji & Co. for a large warehouse roof project in Chennai. The rods passed cleanly through the purlin webs without any field bending — erection was quick and tidy. Dimensions were accurate to drawing and delivery was on time. Will definitely order again for our next PEB project.

Manoj D. Erection Lead, PEB Contractor, Chennai
★★★★★

Ordered hot-dip galvanised sag rods for a coastal industrial shed near Mangalore. Even after two monsoon seasons, the rods have stayed completely rust-free. Thread quality is consistent and lengths were exactly as specified. E S Haji & Co. is now our go-to supplier for all corrosion-resistant fastener requirements.

Suresh B. Site Engineer, Mangalore
★★★★★

We needed bulk sag rods along with hillside washers and brace rods for a multi-shed factory project in Bangalore. E S Haji & Co. supplied everything together — one source, one invoice, no coordination hassle. MTCs were provided with the batch and lead time was well within our project schedule. Highly recommend for large procurement orders.

FAQ

Frequently Asked Questions

Common questions about our sag rods (z sag rods) manufacturing and supply.

  • What is a sag rod?

    A sag rod is a threaded steel rod installed between purlins or girts to support them against sag and lateral load from roof and wall sheeting. It ties the purlin line together and transfers load to the rafter or eave, keeping members aligned.

  • What is a Z sag rod?

    A Z sag rod is a sag rod bent in a Z profile so it passes cleanly through the web of Z and C purlins. The bent shape makes installation fast and the connection tidy without extra brackets.

  • What sizes and lengths of sag rods do you make?

    We manufacture sag rods from M10 to M24 in lengths set by your purlin spacing, with single lengths up to 12 metres available on request.

  • What is the difference between a sag rod and a brace rod?

    A sag rod runs perpendicular to the purlins to prevent sag and lateral deflection along the purlin line. A brace rod runs diagonally between frames to provide lateral stability to the overall structure. Both are used together in PEB and industrial shed bracing systems.

  • Are sag rods galvanised for outdoor roofs?

    Yes. We offer hot-dip galvanised and stainless steel sag rods for coastal, chemical and outdoor roof structures where corrosion resistance is needed.

  • Which standards apply to sag rods?

    Our sag rods are made from IS 2062 / ASTM A36 structural steel with threads to IS 1367 / ISO 898-1, in grades 4.6, 5.6 and 8.8 as required.

  • Do you supply sag rods PAN India?

    Yes. We supply sag rods - with hillside washers, brace rods and connectors - across all major Indian cities with reliable lead times and MTCs.

  • Do you supply hillside washers with sag rods?

    Yes. We supply hillside washers along with sag rods for sloped roof purlin installations. Ordering together ensures correct fit and saves procurement time on site.
