After Sale Service

Ensuring Long-Term Structural Performance Beyond Project Handover

After Sale Service for Pre-Engineered Buildings and Steel Structures

In industrial steel construction, structural performance does not end at project handover. The long-term reliability of a pre-engineered building depends on correct installation, controlled usage conditions, periodic inspection, and timely technical intervention when required. An effective after sale service framework ensures that the structural system continues to perform according to its original design assumptions, load parameters, and code compliance requirements.

KMS Technologies provides structured after sale service support for all pre-engineered buildings, standard frame types, secondary structural systems, roof and wall systems, mezzanine platforms, and crane-supporting structures manufactured and supplied by our facility. Our service framework is built around engineering validation, structural performance monitoring, and controlled corrective measures.

All manufactured components are covered under a one-year warranty against manufacturing defects. This warranty applies strictly to fabrication-related defects in primary steel members, secondary members, connection components, and factory-manufactured cladding systems, subject to proper installation and usage conditions.

Scope of After Sale Service

After sale service for structural steel systems must be clearly defined to avoid ambiguity. Our support team covers engineering review, defect assessment, structural integrity evaluation, and corrective recommendations within the warranty period and beyond under applicable service contracts.

The scope includes:

  • checkmark Assessment of manufacturing defects within one year of project handover
  • checkmark Technical evaluation of structural members exhibiting abnormal behavior
  • checkmark Inspection of bolted and welded connections for fabrication inconsistencies
  • checkmark Review of roof and wall panel performance related to factory-manufactured defects
  • checkmark Verification of secondary structural components such as purlins, girts, and bracing members
  • checkmark Engineering guidance for structural modifications or load changes

One-Year Manufacturing Defect Warranty

Warranty Coverage

KMS Technologies provides a one-year warranty covering manufacturing defects in fabricated steel components and factory-processed cladding systems.

What Constitutes a Manufacturing Defect

A manufacturing defect refers to a deviation arising during fabrication, material processing, or factory quality control that affects structural performance. Examples include:

  • checkmark Dimensional deviation beyond approved fabrication tolerances
  • checkmark Incorrect plate thickness or material grade supplied against approved drawings
  • checkmark Improper welding execution leading to compromised joint capacity
  • checkmark Surface treatment defects affecting corrosion protection
  • checkmark Incorrect hole alignment impacting bolt force transfer

Warranty Conditions

The warranty applies only when:

  • checkmark The structure has been erected as per approved GA and erection drawings
  • checkmark No unauthorized modifications have been made
  • checkmark Loading conditions remain within the design limits
  • checkmark Maintenance procedures have been followed as advised

Warranty Exclusions

The warranty does not apply to damage caused by misuse, accidental impact, overloading, improper maintenance, environmental exposure beyond design assumptions, or third-party structural alterations.

Technical Evaluation and Service Methodology

When a service request is received, the response is engineering-driven rather than administrative. The evaluation process follows a defined technical protocol.

Document and Drawing Review

The service team gathers:

  • checkmark Approved structural drawings
  • checkmark Fabrication details and material test certificates
  • checkmark Erection methodology records
  • checkmark Site photographs and current structural condition documentation
  • checkmark Load usage information, including crane loads if applicable
Technical Evaluation of Steel Building Structural Drawings

Structural Performance Assessment

The structural system is reviewed to understand load paths and force transfer mechanisms. Primary frame members such as tapered columns and rafters are checked for:

  • checkmark Excessive deflection
  • checkmark Local buckling
  • checkmark Connection slippage
  • checkmark Stress concentration near haunch or splice locations

Load Path and Connection Verification

Secondary structural components are reviewed for:

  • checkmark Purlin and girt alignment
  • checkmark Bracing tension integrity
  • checkmark Fastener pull-out resistance
  • checkmark Oil canning in cladding panels due to support misalignment

Root Cause Analysis

The purpose of this evaluation is to determine whether the issue originates from manufacturing or from site-level factors.

Corrective Action and Rectification Protocol

If the issue is confirmed as a manufacturing defect within warranty coverage, corrective action is initiated without ambiguity. If the issue arises from non-manufacturing causes, a detailed technical advisory is provided outlining the required rectification measures.

Preventive Maintenance Advisory

A steel building is designed for specified load combinations and environmental exposure categories. Long-term performance depends on proper maintenance. We provide structured maintenance guidelines, including:

  • checkmark Periodic verification of bolt torque
  • checkmark Visual inspection for signs of corrosion
  • checkmark Removal of debris from roof panels
  • checkmark Inspection of drainage systems
  • checkmark Monitoring of crane impact zones

Preventive maintenance reduces the likelihood of structural degradation and extends service life.

Documentation and Compliance Protocol

All after-sale service actions are documented for traceability and accountability. Documentation includes:

  • checkmark Site observation reports
  • checkmark Photographic evidence
  • checkmark Engineering calculations, where applicable
  • checkmark Details of rectification procedures
  • checkmark Confirmation of compliance after corrective action

Traceable documentation is essential for industrial clients, especially when facilities are subject to compliance audits or insurance reviews.

Service Request and Response Process

Service efficiency relies on clear communication and availability of technical data. The standard response workflow includes:

  • checkmark Submission of a formal service request with issue description
  • checkmark Review of technical data
  • checkmark Remote evaluation, where feasible
  • checkmark Site visit, if required
  • checkmark Issuance of an engineering report
  • checkmark Implementation of corrective action under warranty, where applicable

This structured framework ensures minimal operational disruption and technically sound resolution.

Limitations and Exclusions

Clear service boundaries prevent disputes. The following are excluded from the manufacturing defect warranty unless explicitly agreed:

  • checkmark Damage caused by impact from vehicles or equipment
  • checkmark Corrosion resulting from aggressive chemical exposure not defined in the original design
  • checkmark Structural alterations by third parties
  • checkmark Overloading beyond approved crane or floor load limits
  • checkmark Improper erection not in accordance with approved drawings

Each claim is evaluated based on engineering evidence.
